This paper dealed with position control problems of a DC motor servo system that had nonlinear friction and was subject to parametric uncertainties
external disturbances
etc. In order to overcame those unfavourable factors mentioned above
a model reference adaptive control method was proposed to regulate the important and main speed loop in the positioning system which was designed with three closed control loop
where a compensatory measure was given so as to counterbalance the friction torque disturbances. In addition
the other two close loops were built in adjusting the position and the current of the servo system respectively that aimed to achieve the fast and precise positioning and increase dynamic stiffness against load disturbances. Experimental results illustrate satisfactory performances in steady state error
load capability
high rapidity and so on. 2010 IEEE.

Fuzzy controller was used to resolve the problem of fast tracking and overshoot in electric-driven simulation turntable
for its essence belongs to PD control In this system
the control rules of fuzzy controller were established according to the step dynamic response process
for the speed loop of this system was predigested to be second-orders system. The describing function method was adopted to analyze the stability of the fuzzy control system. It gave the information of stability of system intuitively. The fuzzy controller had been applied in this system successfully. The simulation turntable had no overshooting nearly when its step input signal was close to 90. Experimental results show the implementation method of fuzzy controller is not only simple but also effectual in engineering practice. It also provides an approach of design of fuzzy controller for motion control system. 2008 IEEE.

The paper presents a method with the technique of combination filtering of spectrum and the technique of DSP control for the simulation and recognition of the spontaneously lightening object and stellar map in the universe. The magnitude and the spectrum of a star can be simulated in a wide dynamic range. We established the mathematical models of the Vega's visible light spectrum and luminous flux density. Tungsten-halogen lamp as a light source is used to fit the linear light of the spontaneously lightening object in the universe. Through the experiment
it shows that the more sub-channels there are while filtering spectrum in the visible spectrum
and the more degrees the variable neutral density filters and the narrow-band attenuators have
more close to the actual spectrum the simulated spectrum is. It is proved that using the PID technique is beneficial to the output of the accurate and steady radiation from the light sources. The experiment shows that the using of this method can get perfect result in fitting and simulating the spectrum
magnitude and the stellar map of the spontaneously lightening object . The analysis of the consistent result and the experimental error is also discussed in detail in this paper.
