分析了变参数PID 控制器各个参数随着误差信号的变化趋势,得到它们的关系表达式。通过这个关系式去实现变参数PID 控制器的参数校正。仿真结果表明能得到比常规非变参数PID 控制器性能更好。 关键词:PID 控制器;变参数;误差信号; The Research of The Variable Parameters PID Governor CHEN Yong-hong ZHU Cong-qiao WAN Yan-ling (Power Eng. College, Naval Univ. Engineering, Wuhan 430033, China) Abstract: Analyzed the variation trend of the Variable parameters PID governor with System error, and received their expression. Revised the parameters of Variable parameters PID governor through the expression. The emulational result indicated the performance of Variable parameters PID governor is more excellent than general PID governor. Keyword: PID governor;Variable parameters; Error signal;
