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.
