Performance Requirements

Although the traditional PID controller is widely used in many fields, the system parameters varying and external disturbances existing in the DC servo system will cause large overshoot or poor stability. To improve the performance of the PID controller, a compound servo control system combining the conventional PID control and the fuzzy control is presented to meet the demand of a vehicular antenna servo system in this paper. Incorporating the fuzzy control and the conventional PID control, this paper presents a design method of the fuzzy PID controller that is based on the fuzzy tuning rules and formed by integrating two above control ideas. Simulation results are presented to show the efficiency of the proposed controller. The practical control effect shows that the control system that adopts the fuzzy PID controller has better performance than that of the traditional PID control system, and meets the performance requirements of the servo system.

Because the classic PID control doesn’t satisfy the demand of automobile ABS in all conditions and it is short of an ability of identifying road surface, fuzzy control is short of an ability of remove systemic stable error and it doesn’t make automobiles keep higher control precisions. a dynamic mode of the wheels is built when an automobile is braking at first, aiming at automobile ABS, a immune PID control algorithm based on classic PID is presented and used in automobile ABS system. Compared with the classic PID control algorithm and fuzzy control algorithm, the simulation result shows that the immune PID control algorithm has a shorter stabilization time, a smaller excess of system output, fewer response time and shorter braking distance, it is superior to the classic PID control algorithm and fuzzy control algorithm. The immune PID control algorithm has a higher application value.
