摘要
针对典型的电液位置伺服系统,将PID控制与重复控制相结合,设计了一种复合控制器。其中,PID控制采用遗传算法对其参数进行优化。计算机仿真表明,复合控制器的应用改善了系统的动态性能,比单纯的应用经典PID控制取得了更好的周期信号跟踪效果。
Aimed at typical electro-hydraulic position servo system, a kind of compound controller which combines PID control and repetitive control was designed. Genetic algorithm was used to optimize the PID adjuster. It is shown by this simulation that, under the control with this compound controller, the electro-hydraulic position servo system can track periodic signal accurately and exhibits quite fair dynamic characteristic.
