Conference Program WCICA 2012 is in the form of Werner-like state (d=0). Botmart, Thongchai Srinakharinwirot Univ. ◮ SuA11-5 14:50–15:10 Quantum chaotic communication, pp.1854–1859 Zhang, Jing Wu, Rebing Li, Chunwen Tarn, Tzyh-Jong Tsinghua Univ. Tsinghua Univ. Dept. Automation, Tsinghua Univ., Washington Univ., St. Louis, MO The attack induced by the eavesdropper will lower the bit rate or even lead to the failure of quantum communication. To solve this problem, we introduce a so-called quantum chaotic communication method to mask and thus actively protect the quantum information by chaotic signal from being attacked. The encoding and decoding processes are realized by transmitting the communicated quantum signals through the auxiliary chaotic devices at both sides of the sender and receiver. The method is applied to two examples, in which continuous-variable coherent states and qubit states are successfully transmitted without being influenced by eavesdropping. ◮ SuA11-6 15:10–15:30 Optimal Control of Quantum Discord in a Common Environment, pp.1999–2004 Song, Hongting Pan, Yu Cui, Wei Xi, Zairong Acad. of Mathematics & Sys. Sci. Chinese Acad. of Sci. Chinese Acad. of Sci. Chinese Acad. of Sci. We get the dynamical evolution of quantum correlation for the general Werner state immersed in a common Ohmic bath. The optimal control can be derived using Pontryagin maximum principle. It is found that the control field obtained is helpful to suppress the environmental noises, in the sense of slowing down the decay of discord and prolonging its existing time. Our numerical work demonstrate that the controlled discord time is almost twice as long as the one without control. ◮ SuA11-7 15:30–15:50 Coherent Quantum Feedback Rejection of Non-Markovian Noises, pp.2209–2214 Xue, ShiBei Wu, Rebing Zhang, Jing Tsinghua Univ. Tsinghua Univ. Tsinghua Univ. This paper explores the control of non-Markovian systems via coherent quantum feedback. In the spirit of classical control theory that is widely used in engineering, we acquire completely new insights in the closedloop design from the frequency domain point of view, which appears missing in quantum control theory. Based on the example of a bosonic system connected to a pair of coupled bosonic baths, a non-Markovian Langevin equation is established to model the closed-loop quantum dynamics. We find that, in contrast to the existing time-domain design methods, the frequency domain analysis is more natural on the memory kernel function, which can be reshaped by feedback to suppress the non-Markovian decoherence. For illustration, we consider the case that the coupling strength in the feedback loop is constant. It is found that the coherent feedback shifts the two components in the original noise spectral function in two opposite directions, thereby makes it possible to suppress the noise near the system’s working frequency. When the system to be controlled is Markovian, this simple scheme needs to be replaced by more careful design due to the flatness of the noise spectrum. As an example, the effectiveness of our scheme is demonstrated in photonic crystal systems. SuB01 15:50–17:50 Room 203A Stability and Stabilization (II) Chair: Zhou, Yingjiang Co-Chair: Dong, Zhe southeast Univ. Tsinghua Univ. ◮ SuB01-1 15:50–16:10 Delay-dependent exponential stabilization for nonlinear systems with interval discrete and distributed time-varying delays via intermittent control, pp.1077–1082 In this paper, the problem of exponential stabilization for a class of nonlinear systems with interval discrete and distributed time-varying delays is studied. The time delay is a continuous function belonging to a given interval. Based on the constructing of improved Lyapunov- Krasovskii functionals combined with Leibniz-Newton’s formula, new delay-dependent sufficient conditions for the exponential stabilization of the systems are first established in terms of LMIs without introducing any free-weighting matrices and independent on the derivatives of the interval time-varying and distributed delays. The controller design are proposed intermittent feedback control. Numerical examples are given to illustrate the effectiveness of our theoretical results. ◮ SuB01-2 16:10–16:30 Shifted-Ectropy Based Self-Stability Analysis Method for General Thermodynamic Systems and Its Application, pp.1406–1411 Dong, Zhe Tsinghua Univ. Self-stability, which is the ability that system state can converge to an equilibrium point without any control input, is one of the most crucial features of every dynamic system. Self-stability analysis is the basis of designing a regulation strategy, and is also one of the key parts of the recently developed physical control theory. For electrical or mechanical systems, generalized Hamiltonian system theory provides a strong tool for not only self-stability analysis but also control law design. However, there is still no mature strategy for analyzing the self-stability of any thermodynamic systems. In this paper, after introducing the con-cepts of irreversibility function and shifted-ectropy for general thermodynamic systems, a new self-stability analysis approach based on regarding the shifted-ectropy as a Lyapunov function is established for general thermodynamic systems. Moreover, this newly built method is applied to analyzing the self-stability of the thermo-hydraulic loop of a modular high temperature gas-cooled reactor (MHTGR) ◮ SuB01-3 16:30–16:50 The Stability of Linear Discrete Time Delay Systems Over a Finite Time Interval: New Results, pp.1459–1464 Debeljkovic, Dragutin Univ. of Belgrade, School of Mechanical Engineering Stojanovic, Sreten Dimitrijevic, Nebojsa Popov, Dejan Univ. of Nis, Faculty of Tech. Univ. of Belgrade, Faculty of Mechanical Eng Univ. of Belgrade, School of Mechanical Engineering This paper gives sufficient conditions for the practical and finite time stability of a particular class of linear discrete time delay systems. Analyzing the finite time stability concept, these new delay-independent conditions are derived using an approach based on the Lyapunov-like functions. The practical and attractive practical stability for discrete time delay systems has been investigated. The above mentioned approach was supported by the classical Lyapunov technique to guarantee the attractivity properties of the system behavior. ◮ SuB01-4 16:50–17:10 Stability Analysis for A Class of Distributed ParameterSwitched Systems with Time-varying, pp.2017–2021 Bao, Leping Fei, Shumin Zhai, Junyong Southeast Univ. Southeast Univ. Southeast Univ. In this paper we consider a class of switched systems governed by Partial Differential Equations on Banach space. We provide the results on stability of infinite dimensional distributed parameter switched systems with time-varying. Sufficient conditions for stability are derived via semigroup theory. ◮ SuB01-5 17:10–17:30 Global asymptotic stability of uncertain nonlinear system with state and input constraint, pp.2695–2700 Zhou, Yingjiang Sun, Changyin Wang, Li southeast Univ. Southeast Univ. Southeast Univ. 214
WCICA 2012 Book of Abstracts: Sunday Sessions Zhang, Jingmei Southeast Univ. In this paper, the problem of global asymptotic stability of a class of uncertain nonlinear system with input constraint is considered. And by using the development of the adding a power integrator technique, an auxiliary design system is used to analysis the effect of the input constraint. In addition, physics constraints of virtual control laws are also considered when pi¿1. Finally, simulations are listed to illustrate the effectiveness of the proposed result. ◮ SuB01-6 17:30–17:50 On Non-Lyapunov Stability of Linear Discrete Time Delay Systems: LMIs Approach, pp.1535–1540 Debeljkovic, Dragutin Univ. of Belgrade, School of Mechanical Engineering Stojanovic, Sreten Dimitrijevic, Nebojsa Popov, Dejan Univ. of Nis, Faculty of Tech. Univ. of Belgrade, Faculty of Mechanical Eng Univ. of Belgrade, School of Mechanical Engineering This paper gives new contributions to the area of non-Lyapunov (finite time stability, technical stability, practical stability, final stability) for the particular class of linear discrete time delay systems. The idea of attractive practical stability is introduced for the first time. Moreover, based on the matrix inequalities and Lyapunov-like functions, some new sufficient conditions under which the linear discrete time delay system is finite time stable are given. Finally, an example is employed to verify the efficiency of the proposed Theorems as well as to show that results derived upon LMIs are less restrictive than those based on a classical approach. To the best knowledge of authors, such results have not been reported yet. SuB02 15:50–17:50 Room 203B Multi-Agent Systems (II) Chair: Thunberg, Johan Co-Chair: Wang, Hanlei Optimization & Sys. theory Beijing Inst. of Control Engineering ◮ SuB02-1 15:50–16:10 Passivity Based Synchronization of Multiple Robotic Agents with Uncertain Kinematics and Dynamics, pp.846–851 Wang, Hanlei Beijing Inst. of Control Engineering This paper studies the synchronization problem of networked robotic systems with uncertain kinematics and dynamics. Passivity of the robotic agents is established through adaptation to both the kinematic and dynamic uncertainties. This input-output passivation framework lays the foundation for the inter-coupling inclusion between the robotic agents, even in the case of non-uniform constant communication delays. An adaptive scheme is proposed to achieve controlled synchronization of the networked robotic systems on strongly connected graphs. With a weighted Lyapunov-Krasovskii function, we show that task-space synchronization errors of the networked robotic agents converge to zero. Simulation results are provided to demonstrate the performance of the proposed control schemes. ◮ SuB02-2 16:10–16:30 Exponential synchronization of complex dynamical systems with delay and derivative coupling via impulse, pp.875–880 Zhu, Yakun Luo, Xiaoyuan Li, Shaobao Guan, Xinping Yanshan Univ. Yanshan Univ. Yanshan Univ. Yanshan Univ. In this paper, the problem of impulsive synchronization of a kind of generalized complex dynamical systems with delay and derivative coupling is investigated. Both the communication delay and derivative coupling, which provide more information about the complex dynamical systems, are considered. Based on a new Lyapunov function and impulsive stability technique that is used to play an important role for the synchronization problem in our research, some new delay-dependent synchronization criteria are proposed. Furthermore, one can find that the considered complex systems are suitable to investigate and simulate realistic complex systems such as networked multi-agent systems. And numerical simulations for two networked systems with six agents are shown to illustrate the effectiveness of our results. ◮ SuB02-3 16:30–16:50 Consensus Control of Networked Nonlinear Systems, pp.914–919 Peng, Junmin Ye, Xudong Zhou, Wei Zhejiang Univ. Zhejiang Univ. Zhejiang Univ. In this paper, we proposed a consensus control for networked nonlinear systems with disturbance and uncertain parameter. The proposed algorithm is combined with adaptive compensation of unknown disturbance and output feedback control to achieve consensus, without knowing the disturbance’s amplitude frequency and phase, as long as the number of different frequencies is known. From the theorem presented in the paper, we can see the topology condition for achieving consensus is the same as networked linear systems. A second-order integrated example is used to illustrate the algorithm. The design procedure is divided into two step: in step I, we design a consensus control law for networked virtual agents by Lemma 1; in step II, we use output feedback control with complete compensation of unknown disturbance for adaptive tracking the virtual agents. ◮ SuB02-4 16:50–17:10 Distributed Attitude Synchronization Control of Multi-Agent Systems with Time-Varying Topologies, pp.946–951 Song, Wenjun Acad. of Mathematics & Sys. Sci., Chinese Acad. of Sci. Thunberg, Johan Hong, Yiguang Hu, Xiaoming Optimization & Sys. theory Chinese Acad. of Sci. Royal Inst. of Tech. This paper addresses the attitude synchronization problem of multiple rigid body agents in SO(3) with directed and switching interconnection topologies. Using the axis-angle representation of the orientation, a distributed controller based on differences between the orientations of agents in a global frame is proposed. In the case of the balanced interconnection graph, the attitude synchronization is achieved with the wellknown mild assumption (that is, uniform joint strong connection). To demonstrate the effectiveness of the proposed control scheme, an illustrative example is provided. ◮ SuB02-5 17:10–17:30 Convergence Analysis for Quantized Consensus of Multi-agent Systems with Directed Topologies, pp.1201–1206 Li, Dequan Anhui Univ. of Sci. & Tech.; Shanghai Jiaotong Univ. Liu, Qipeng Wang, Xiaofan Shanghai Jiao Tong Univ. Shanghai Jiaotong Univ. The available works about quantized average consensus require the update matrices being doubly stochastic, which amounts to confining agents to evolve on balanced digraphs with quantized information communication. By dropping the typical double stochasticity requirement for the update matrix, we revisit an existing average consensus protocol based on logarithmic quantization scheme and study the quantized consensus problem for general directed networks. An upper bound for the quantization precision parameter is derived to design the suitable logarithmic quantizer, then based on matrix transformation and Lyapunov technique, we provide testable condition under which the weighted average consensus can be achieved with the proposed quantized protocol. The proposed quantized protocol features little communication protocol overhead and suits well for directed digital networks. ◮ SuB02-6 17:30–17:50 Distributed Attitude Synchronization Control of Multi-Agent Systems with Directed Topologies, pp.958–963 Thunberg, Johan Song, Wenjun Optimization & Sys. theory Acad. of Mathematics & Sys.
