The traction converter system of EMU is constructed based on Matlab/Simulink.
The system consists of a transformer, a rectifier, an inverter
and an induction motor. The rectifier is controlled by the transient
current control theory with SPWM technology. In the inverter the indirect
vector control theory with current hysteretic band PWM strategy is
adopted. Based on the system the traction control and constant speed
control are tested. The simulation results present that the system is
with good dynamic and steady state performance and fulfill the running
demand of EMU.

This paper develops stability and stabilization theorems for a class of
quadratic systems with state saturation nonlinearities. Based on the
introduction of a row diagonally dominant matrix with negative diagonal
elements and a particular representation for the quadratic terms,
sufficient conditions for stability and stabilization of quadratic systems
with state saturation nonlinearities are derived in terms of a “quasi”
-linear matrix inequality (LMI) form. Iterative LMI algorithms then are
presented for checking global asymptotic stability and stabilization of
the system. Numerical examples are provided to demonstrate the effectiveness
of the proposed approach.

In order to optimize the flight thrust performance, this article brings forward
the concept of thrust management system (TMS). The TMS is
composed by thrust management computer, auto throttle (A/T), engine
control system and cockpit control and display system. This article analysis

accord with flight quality guideline well. This research bases a
foundation for further research of the thrust management, which has
significant meaning for increasing the flight security management level,
saving fuel and decreasing flight cost.

According to the disadvantages of general PID controller parameters
optimization methods, this paper presents an improved immune algorithm.
Main characteristics of this algorithm is to generate an initial
population using homogenization techniques, self-adapt crossover operator
and mutation operator. Result of simulation shows that the new
method is superior to Z-N optimization algorithm. This method can
overcome the premature phenomenon effectively and has good convergence
performance and optimizing capacity.

Delay-dependent Robust Stability for Markovian Jump Singular Systems
with Disturbances, pp.1340–1343
Cui, Wenxia
Donghua Univ.
This paper is concerned with robust stability problem for Markovian
jump singular time-delay systems with disturbances. In terms of strict
linear matrix inequality(LMI), a new necessary and sufficient condition
is proposed for the unforced Markovian jump singular system to be s-
tochastically admissible. Based on this, the sufficient conditions are obtained
for the existence of performance, which guarantees the singular
Markovian jump systems with disturbances to be regular, impulse-free
and stochastically stable. One numerical example is given to demonstrate
the applicability of the proposed method.

We proposed a robust adaptive control method for trajectory tracking of
underactuated surface ship with parameters uncertainties and disturbances.
Based on the diffeomorphism transformation, the new tracking
variables are given. In kinematics loop, we design the reference yaw
angle and the reference speed. The nonlinear adaptive controller is
designed in dynamics loop to asymptotically approach to the desired
variables. The stability of the closed-loop system is analyzed by using
Lyapunov theory. Simulation results illustrate the effectiveness of the
proposed control method.

Regional pole assignment is studied for a class of linear systems via
static output feedback. The shortage of the optimization problem
subject to a set of bilinear matrix inequalities(BMIs) is analyzed. Then
the algorithm of static output feedback pole assignment based on the
regional attractors is proposed. A set of attractors in the satisfactory
region is determined firstly. After that, the optimization direction of
the output feedback matrix can be obtained via the one-dimensional
searching method of variable polling. And a feasible solution can be
attained by iterative computation. Computational results are presented
demonstrating the effectiveness of the provided algorithm.

Considering the different time that platoon reaches downstream intersection,
this paper proposes corresponding stop and delay coordinated
control models for under-saturated and over-saturated traffic conditions.
With the cumulative arrival-departure diagrams, uniform stop and
delay models for under-saturated and over-saturated traffic conditions
are proved to be consistent and accurate by formula derivation. It provides
a basis on deducing the stop and delay general formulae under
signal coordinate control mode theoretically.
