To solve the fuzzy control rule being difficult to change with the status
variation in water temperature and mixed solidification and so on, the
paper presented a sort of fusion control strategy based on human intelligence
simulated. It studied the purified process such as mixed solidification
and so on, analyzed the impact factors of mixed solidification,
summarized the cybernetics characteristic, and constructed the engineering
control algorithm based on human intelligence simulated. And
it took one order model with large lag and inertia as an example to make
simulation respectively by the presented algorithm and PID, compared
the response curve in control quality, anti-jamming, and robustness of
parameter change, it indicated the former being quicker in response
time, and higher in control precision. The simulation results show it is
strong in adaptation and robustness to the controller constructed by the
presented control strategy.

Motor servo control system is of nonlinear, multivariable, strong coupling.
A scheme of sliding mode control is proposed based on particle
filter for position tracking system. Simulation results show that system’s
tracking performance is much better than Kalman filter, and it can significantly
improve the system dynamic performance and robustness.

With regard to the aircraft flutter flight test stochastic models coexisting
input and output observation noise, this paper deduces the simplified
form of the maximum likelihood cost function about the stochastic model
by virtue of the frequency domain maximum likelihood estimation
principle. Then a global optimization iterative convolution smoothing i-
dentification method is derived to significantly reduce the possibility of
convergence to a local minimum and weakly dependent of the starting
values’choice by using the global optimization theory. The identification
method modifies the iterative method with a stochastic perturbation
term and guarantees the algorithm converge to a global minimum. The
simulation with real flight test data shows the efficiency of the algorithm.

Two-wheeled self-balanced becomes a typical device to test various
control method because of its unique characteristics. The sliding mode
of VSC (Variable Structure Control) has strong robustness, so it is
applied to the two-wheeled self-balancing vehicle would be a great advantage
,but there is few research on it. To realize the computer control
based on the discrete variable structure controller, we have to research
the sampling period. In this paper, we give a method to find the longest
sampling period of VSC based on two-wheeled self-balanced Vehicle.

One nearspace hypersonic aircraft model based on pneumatic/ thrust
vectoring composite control was built, compound controler optimization
scheme was adopted to cooperate pneumatic/thrust vectoring compound
controler equivalent dynamic characteristic to reference model
during dynamic assign.In the course of adaptive backstepping design,
the dissertation employes the dynamic surface control strategy to eliminate
the explosion of terms by introducing a series of first order filters to
obtain the differentiation of the virtual control inputs. Lyapunov stability
theorem guarantees the error uniformly bound. Both theory analysis
and 6 DOf simulation verification show the simpleness and arithmetic
availability.

This article reviews and compares several aspects of permanent magnet
synchronous motor speed control method of the anti-windup. In
generally, motor control aspects of the state equation is modeled as
linear systems in real-time control systems, at the same time the system
will generate much higher than normal current and voltage values.Therefore,
PI control is likely to have links to over-amplification of
the control value, This phenomenon is called over-saturation of the motor,
The existence of this phenomenon will cause the system to nonnormal
operation, causing system instability. So we will see in the article,
several anti-saturation control algorithms, they will be in permanent
magnet synchronous motor sensorless vector control algorithm and
control algorithm for anti-saturation control and the speed controller in
its use, to reduce saturated part of the motor speed, and the comparison
of each other.

A new two-degree-of-freedom control structure is proposed for cascade
control systems. Analytical method of controller design is derived for
the general process model. Its dominant merits are that the primary
deficiency of tuning trouble occurring in a conventional cascade control
system is essentially overcome. With this structure, the set-point tracking
and disturbance rejection property of primary and secondary loop
are no longer coupled. Meanwhile, the approximation for the closedloop
transfer function of the secondary loop is no longer necessary
in the design of primary loop controller, so the system control performance
is improved. The simulation results demonstrate that the proposed
method is superior to the existing methods.
