时滞对象的自适应Smith预估控制方案

Selfadaptive Smith Preestimation Control Scheme for Timedelay System

摘要: 针对时滞被控对象提出了一种自适应Ｓｍｉｔｈ预估控制方案，利用变遗忘因子递推最小二乘法进行参数在线辨识以构成Ｓｍｉｔｈ预估器，采用模糊神经网络控制器完成对被控对象的控制。仿真结果证明了这种方法的有效性。

Abstract: The paper presents a selfadaptive smith preestimation control scheme for timedelay system. Smith predictor makes up of identificable parameter using RVFF(Recursive Variable Forgetting Factor Method) on line. FNNC (Fuzzy Neural Network Controller) is used as system controller. The simulation results show that the method is effective when parameter is changed.
