摘　　要：由于PID控制器的结构限制,将它用于具有振荡、积分或不稳定传递函数的被控过程时,无法得到好的闭环特性,系统的阶跃响应往往具有大的超调且会产生振荡。而若用PI-PD控制器来控制上述被控过程,可以得到满意的闭环特性。介绍了通过PID控制器参数得到PI-PD控制器参数的简单方法,并通过仿真举例证明了方法的正确性。The closed loop performance is not so satisfying when use it to the process that has resonance, integrate or unstable transfer function, and the step response usually has excessive overshoot and vibration , due to its structure limitation,in this case, we can get more satisfying response by using PI - PD controller. A simple method to obtain the parameters of the PI - PD controller through the parameters of the PID controller was introduced, and the simulation examples proved the validity of this method.
