摘要
采用Smith型时滞补偿器,对于具有未知或时变时滞的二阶(或一阶)开环稳定被控过程,分别提出了以任意稳定裕度和极点配置为指标的自校正PID(或PI)控制算法。仿真结果表明,该算法简单可行,且易于实施。
By using a Smith-predictor type of lime delay compensator, the self-tuning PID (or PI) control algorithms based on the arbitrary stable margin and the pole-placement are respectively proposed to handle second-order (or first-order) open-loop stable processes with unknown or varying time delays. The simulation results show that these algorithms are simple, applicable and convenient for the applications.
