A new variable separation in the (G ′ /G)-expansion algorithm is introduced
to obtain the solutions for a nonlinear Broer-Kaup system with
variable coefficient. Control based on the variable coefficient is studied
for the system. Different variable coefficient functions greatly influence
the traveling way, velocity and amplitude of the solutions. Visualized
effects are plotted.

Average Dwell-Time Approach to Stabilization of Networked Systemswith
Actuator Saturation, pp.2097–2102

The output feedback control problem is studied for networked discretetime
systems with actuator saturation and packet losses. The proposed
output feedback controller is both saturation-dependent and packetloss-dependent.
The resulting closed-loop system is expressed as a
switched discrete-time system. A sufficient condition for the local and
asymptotic stability of the closed-loop system is developed by using
an average dwell-time approach and a saturation-dependent Lyapunov
function. The output feedback control law is then proposed in terms of
linear matrix inequalities.

Modern robust control theory was brought in the parameters design of
tank stabilizers for ship, which can solve the nonlinear and model uncertainty
exist in ship-tank-stabilizer system. An objective function for
parameters optimization of tank stabilizers was established, which is
suitable for tanks of different structure and system composed of multiple
tanks. The simulation result shows that the stabilizers designed
with this method can provide more effective roll reduction under nonlinear
condition. And the double-tank system had more effective roll
reduction in extended frequencies.

According to trajectory tracking problem in terrain survey mission, trajectory
scheduling and control method is researched for unmanned underwater
vehicle (UUV). Cross track error and line of sight combined
guide is used for trajectory indirect control. In order to ensure precision,
track and heading error are both used to switch guide method.
Meanwhile, inserting medi-task scheduling strategy is used to improve
the survey effect. Compared with ordinary strategy, it can improve stability
while task switching and reduce overshoot and oscillation. At last,
the results of lake trial are present, which show that combined guide
method is effective. By compare with two different scheduling trials, the
results indicate that medi-task scheduling strategy can improve control
character while task switching, and increase control precision, which is
advantageous for terrain survey.

Fractional order QFT Controller for Nonlinear Systems, pp.2136–2141
Meng, Li

This paper presents the design of a robust fractional order controller for
the nonlinear RC circuit based on quantitative feedback theory (QFT).
In this work, a fractional-order compensator, with a flexible controller
structure, is introduced into the QFT design to give a better approximation
of optimum open loop in Nichols. It has been demonstrated that
the fractional order controller can provide smaller high frequency gain
than the integer order controller due to its extra tunable parameters.

As the network is introduced into the system, it will increase complexity
of system dynamics and plant modeling, data-driven control theory
is proposed to design the controller independent of the model in this
paper. Construct the output data matrix and the input data matrix using
input / output current data and historical data, establish a linear
relationship between the two, thus get the predictive controller gains.
Simulation results show that the proposed controller is effective.

Cross-Layer Energy Efficiency Design in Wireless Sensor Networks,

Based on the analysis of the reliability and energy-consumption in
WSNs, In this paper, we propose a cross layer-based MAC protocol
abbreviated as CoDyMAC(Cross-layer and Dynamic balance energyconsumption
MAC). CoDyMAC realizes multi-hop data transmission in
a listen / sleep cycle by utilizing the interactions among MAC, Routing
and Physical layers, and meanwhile introduces the selection mechanism
of communication node and take the redundancy under control
after weighing the energy-consumption and the reliability of data transmission.
Thus it dynamically balances the energy consumption and
prolongs the network life. Through the performance analysis and the
simulation study, CoDyMAC shows its advantages such as shorter latency,
lower energy-consumption, and high reliability to SMAC, ASMAC
and ELMAC.
