摘　　要：针对电液位置伺服系统的特点及其性能要求,在传统PID控制基础上设计出一种基于干扰观测器的PID控制器。该控制器可以观测出等效干扰,并在控制中引入等效的补偿,可实现对干扰的完全抑制。在MATLAB环境下对该系统进行了动态仿真。仿真结果表明,该控制器具有很好的快速响应特性、较强的鲁棒性和较高的跟踪精度。According to the trait and performance requirement of the electro-hydraulic position servo system, and based on the traditional PID control, a kind of disturbance observer based PID controller was designed. The controller can observe the equivalent disturbance and introduce equivalent compensation and restrain the disturbance completely. The dynamic simulation of the system was processed based on MATLAB environment. Simulation results show that the controller achieves faster response characteristic and stronger robustness and higher tracing accuracy.
