一类热工不稳定滞后对象的补偿控制方法
Compensation control method for integrative﹣plus﹣dead﹣time process
摘要
Abstract
The Smith prediction compensation algorithm can not be used for unstable dead﹣time processes control directly.In order to make the compensation control of Smith predictor be stable in closed﹣loop sys﹣tem,a dynamic general controller was applied to the integrative﹣plus﹣dead﹣time model.This method takes full use of the feedback control of velocity and acceleration,which improved control quality of the system. Moreover,the meaning and determining method of instability correction factor Kp was given.The simula﹣tion results show that this method has good robustness,few adjustable parameters and simple configura﹣tion,which is convenience to the actual application.关键词
