The control of the planar vertical takeoff and landing (PVTOL) aircraft
is a hot research problem. This paper introduces a two-order cascade
Tornambe’s controller(TC) to PVTOL model after change one time,
and then compares with other TC control methods. The simulation
shows that the method of this paper also has a good performance on
tracking, disturb rejection and performance robust. Because it has a
simple construction and is easy to adjust parameters, so the method of
this paper is a control method to select.

A co-design scheme of static period quantized scheduling and the state
feedback controller for a class of networked control system with limited
bandwidth and fixed time delay using mid-tread uniform quantizers is
proposed in this paper. Through allocating bandwidth, the quantized
scheduling strategy and feedback controller design are considered simultaneously.
The quantized measurement signals are dealt with by
utilizing the sector bound method, in which the quantization error is
treated as sector-bounded uncertainty, and the NCS is modeled as a
discrete-time switching system with parameter uncertainties. Based on
the Lyapunov function and period switching system theory, a design
procedure for feedback controller under this strategy is given to maintain
the asymptotic stability of closed-loop system.

Based on support vector machine theory, a generalized predictive controller
is designed for turboshaft engine. Using dynamic response data,
through support vector machine regression, the turboshaft engine nonlinear
model is established. By linearizing the nonlinear model at each
sampling cycle, the prediction model of turboshaft engine is constructed.
According to generalized predictive control algorithm, the optimal
control signals are obtained. Simulation results show that the control
system can follow the change of collective pitch very well, the speed
of power turbine can back to given value fast and possess small overshoot.

Stock turning point has been playing a significant role in the stock investment
as buying or selling stocks around it can make a good return.
The existing methods recognize the turning points according to different
types of features but the effect is not so satisfactory. In this paper, we
firstly build multiple types of features what reflect many aspects of characteristics
of stock and utilize mutual information to partition them into
several subsets. Then we use SVM to train the turning point recognition
model on every feature subset. Finally, we combine the multiple models
into an ensemble and apply Particle Swarm Optimization (PSO) to
optimize the combination coefficients. Experimental results show that
our method is more effective.

In view of extreme points of the Delphi method, this paper introduces
the penalty factor to improve it and overcome the influence of subjective
factors. Then, it applies the improved Delphi method to determine
weight factor of stroke rehabilitation evaluation indicator in the context
of stroke rehabilitation evaluation system. Simulation results show the
effectiveness of the improved method.

A Study on the System Structure of Multi-UCAV Cooperation Mission
Planning, pp.4030–4034

Mission planning for multi-UCAV cooperation is one of the keys to
take the advantages of multiple UCAVs combating cooperatively and
to maintain harmonies between the mission complexities and UCAV a-
bilities. A distributed and concentrated composite architecture of multi-
UCAV cooperation mission planning system was constructed. Based
on the analysis of the cooperative UCAVs mission hierarchy, a hierarchical
and iterative mission planning frame was introduced. The logic
architecture of multi-UCAV cooperation mission planning system was
put forward, and two key sub-problems, that is mission assignment and
path planning, were analyzed.

Abstract―With the development of power industry, power plants have
been expanding. So in the planning and design, construction and operation
stages, there is a wealth of information produced. However, the
information management in all power plants are all complex and not
standardized, which make the management’s work very inconvenient,
and that include all system, equipments and etc. In order to achieve
the standardization and intelligent management, hydropower industry is
placing more importance on the ERP implementation,while the core
foundation data of the ERP system are from the device code. On the
basis of a comprehensive study of domestic and foreign industrial applications,
building the encoding software in the identification system of
hydropower plant has been studied and corresponding design and instances
of system are given. This paper studies achieves the management
of the power plant information code and laid a stable foundation
for the implementation of the ERP project.

Nuclear power around the world has shifted to expand the lifetime of
nuclear power plant as long as possible on the condition of safety and
reliability instead of constructing new ones. In order to achieve the
goal of life extension, the nuclear power plant all attach great importance
to the life cycle management of critical equipment. LEA is a core
of the life cycle management of critical equipment and an analysis s-
trategy to improve the usability of critical equipment and achieve the
maximization of life value and long period of revenue through optimiz-
