SMITH预估补偿控制的改进型算法

Modification Method for SMITH Estimating Precompensation Control

提出了一种改进型 Smith预估补偿控制方法。在被控对象的输入端施加一阶跃输入信号 ,根据其阶跃响应估计出被控对象的数学模型 ,再根据此估计模型在线地修正Smith预估补偿器 ,从而克服了传统的

In this paper,a improved method for Smith prediction controller was studied. A step fiction signal was input to the object controlled.Accoridng to the response signal induced by the step fiction signal,a mathematic model of the estimated object was built using the mathematic model,and the Smith prediction controller can be modified on line.This method overcomes the disadvantage of the control quality due to the model error made by the traditional Smith prediction controller.
