Application of predictive control algorithm in speed control system

Abstract

In view of DC speed control system, this paper presents a predictive control algorithm to replace traditional PID control. System predictive model requires little information of the controlled object, and because it adopts rolling optimum method, system possesses excellent dynamic and static performance. According to the practice results, it owns outstanding speed regulating and tracking property. Full digital system hardware improves system reliablity and it is easy to be adjusted. To reduce CPU’s complex calculation, we have studied and developed a digital hardware trigger. The trigger’s identical waveform and steady trigger pulse greatly facilitates system design work and improves system’s overall quality of antidisturbance. This device surely owns a prosperous prospect.
