摘要
自动控制系统的前向通道采用PI控制,而反馈环内加入PD控制,由此构成了PI-PD控制器。PI-PD控制器不仅具有与PID控制相似的功能,并且对于含有积分、振荡或不稳定环节的控制对象,可以实现较好的闭环控制。本文介绍了PI-PD控制器的结构和参数计算方法,将该控制器应用于一个随动系统中,通过仿真分析,表明了PI-PD控制器的特点和优越性。
This paper discusses the control system where the PI controller is in the forward loop and the PD controller is in the feedback loop. The PI-PD controller provide better closed-loop performance than the PID controller for plants with resonances, integrators or unstable transfer function. A servo system example is also presented.
