摘要
针对工业中常用的电液(比例)位置伺服系统,给出了基于死区补偿的PDF(Pseudo-Derivative-Feed-back)控制器的设计。仿真试验结果表明,它不仅能大大提高系统的响应速度,有效地消除静态误差,消除了传统PID控制中存在的微分突变现象,还表现出对系统参数变化的较强鲁棒性,使得它能够很好地满足设计性能要求,控制效果明显优于传统PID控制。
Aiming at electro -liquid position s ervosystem is common used in industr y,design of PDF controller based on dead zone compensatory is pr esented in this paper.Emulate resul t indicates:it not only enhances response -velocity of system,elimi nates static state error effectively,but also eliminates differential coefficient mutation phenomenon in tradition PI D control.Simultaneity,it puts up b etter robusticity to system parameter variety in emulate examination.Con trol effect excels traditional PID c ontrol in evidence.
