迟延时间过程和预估控制方法

The Process with Delay time and Pre-estimate Control Method

对具有大迟延时间的受控过程,本文分析了Smith理想预估器的控制性能;研究了预估器插入串级调节系统的正确方式;分析了模型参数误差对控制性能的影响;对参数误差的影响进行了仿真计算;提出了简化模型预估控制方法。

For the controlled process with big delay-timer, the paper analyzes the properties of control system with prefect Smith pre-estimator, studies the correct form into cascade control system, analyzes control properties influenced by the parameter＇s error in the system model, makes the calculated simulation for influenced quantity of parameter＇s error, and presents control method by reduced pre-estimate model.
