Evacuation in an emergency is always an important issue for large<br />
buildings. The purpose <strong>of</strong> evacuation is to evacuate people in the shortest<br />
possible time from a dangerous area to a safe place. In order to<br />
complete the evacuation mission effectively, an effective algorithm is<br />
needed. The proposed evacuation algorithm in this paper made a reasonable<br />
model for the building and then starting from a single evacuee,<br />
using recursive methods to get an optimal evacuation plan. This algorithm<br />
overcomes the limitation <strong>of</strong> fast flow control algorithm which can’<br />
t be applied in a multi-SN situation. Besides, because <strong>of</strong> the low complexity<br />
<strong>of</strong> the algorithm, it can be used in real-time environments.<br />

In energy intensive enterprises (EIE) with self generation power plant,<br />
real time electricity cost is affected by dynamic change <strong>of</strong> its power<br />
consumption and generation. Centralized power demand control is<br />
usually hard to be used in EIE due to complex constraints <strong>of</strong> production<br />
process. A rational price signal which is able to lead end users to reduce<br />
power during peak hours or shift load from peak hours to <strong>of</strong>f-peak<br />
hours is valuable. A dynamic pricing mechanism in microgrid for EIE<br />
is researched in this paper, aiming at reducing total electricity cost <strong>of</strong><br />
EIE. By typical case study, some reference ideas about dynamic pricing<br />
problem for EIE microgrid are presented.<br />

The scheduling problem <strong>of</strong> reservoir hydroelectric station during the<br />
flood season caused major concern in academia and industry many<br />
years. Due to the uncertainty <strong>of</strong> flood, the schedule strategy should<br />
guarantee the enough flood prevention capacity <strong>of</strong> hydroelectric, meanwhile,<br />
a certain water head should also be kept in order to guarantee<br />
the power generation efficiency. Therefore, it’s a challenging to design<br />
the strategy <strong>of</strong> optimal scheduling for hydroelectric in flood season.<br />
This paper in response to this objective, online algorithm will be<br />
applied here to analysis optimal strategy, which manages the reservoir<br />
scheduling in terms <strong>of</strong> online strategy and competitive analysis. Then<br />
the evidence from Ankang reservoir are collected to test the competitive<br />
ratio <strong>of</strong> online strategy. The result and model <strong>of</strong> the study in this<br />
paper have guiding significance and reference value to decision makers<br />
facing the similar situation.<br />

This paper is concerned with the problem <strong>of</strong> teleoperation systems over<br />
networks. As is well known, quantization and time delay are unavoidable<br />
in computer network communications. Compared with previous<br />
work, we consider both <strong>of</strong> them when analyzing such systems. The<br />
controller used in this paper is proportional-derivative(PD) controller,<br />
but the output signals <strong>of</strong> master and slave systems are quantized before<br />
being communicated. New criteria are presented to show that the<br />
controller can stabilize the master-slave system under variable time delay<br />
and quantization. Finally, simulations are given to demonstrate the<br />
effectiveness <strong>of</strong> our results.<br />

A self-balancing unicycle robot, which has a wheel for balancing and<br />
movement in the longitudinal plane (pitch angle) as well as a flywheel<br />
for balancing in the lateral plane (roll angle), is studied in this paper.<br />
The non-linear dynamic equations <strong>of</strong> the unicycle robot on a slope are<br />
analyzed using the Lagrangian dynamic formulation, then a linear model<br />
<strong>of</strong> the robot is derived at the equilibrium point, and 3 linear quadratic<br />
regulators (LQR) are designed to control the robot on slopes with the<br />
angle <strong>of</strong> inclination varying from -11°to 11°. Simulation results validated<br />
that the unicycle robot can achieve good performance both on<br />
level plane and on slope.<br />

System modeling and controller design for an in-plane morphing wing,<br />
which is proposed by NextGen Aeronautics, Inc., are investigated in the<br />
present paper. The model <strong>of</strong> the morphing wing is developed based on<br />
Lagrange method. The elastic forces <strong>of</strong> the skin and the aerodynamic<br />
load acting on the leading edge are both taken into account. The generalized<br />
forces are obtained by virtual work principle. Since the morphing<br />
wing is a strongly coupled, over-actuated and nonlinear system with<br />
multi-input and multi-output, the control system design includes a control<br />
allocator, a dynamic inversion controller and two PID controllers.<br />
The control allocator is designed base on pseudo inverse method; the<br />
dynamic inversion controller is applied to make the original system decoupled<br />
into two independent linear systems by proper nonlinear feedback<br />
transformation; two classical PID controllers are adopted for the<br />
linearlized systems. The correctness <strong>of</strong> the model is verified by ADAMS<br />
simulation and the effectiveness <strong>of</strong> the control system is tested by Matlab.<br />
The results indicate that, integrating Lagrange equation, pseudo<br />
inverse control allocation, dynamic inversion control and classical PID<br />
method, is an effective way to solve problems <strong>of</strong> modeling and control<br />
for morphing wings.<br />

The present micro aerial vehicle (MAV) is lack <strong>of</strong> maneuverability and<br />
security when operates in the restricted environment. To solve such<br />
problem, a rotor powered disk-type autonomous aircraft–Micro Aerial<br />
Robot(MAR) was designed, which adopts built-in blades and redundant<br />
actuators structure to enhance vehicle’s safety and robustness<br />
,and adopts the inner and outer two rotor systems and disk-type airframe<br />
structure, which help the MAR has better aerodynamic characters<br />
and maneuverability compared to the common MAV. The six degrees<br />
<strong>of</strong> freedom (6 DOF) dynamic model was built using the Newton<br />
