系统内模控制器设计及仿真

Design and simulation of an internal model controller

将系统的滞后环节用Taylor级数展开 ,根据内膜控制原理设计控制器 ,并利用Matlab软件对响应进行仿真 .仿真结果表明 ,内膜控制与传统PID反馈控制比较 ,其动态性能更好 .内膜控制器设计简单方便 ,具有一定的实用性 .

This article describes the design of the controller according to the internal model control mechanism after to spread out the delay segment on first-order Taylor series, and simulates using Matlab. The result indicates that the dynamic function of internal model control is excellent compared it with PID feedback control. The designe of internal model controller is very simple and practically.
