针对过程控制中存在的大迟延问题 ,采用 Smith预测控制并介绍该控制系统的整定方法 ,给出了两种极点配置的算法 :基于 ITAE准则的整定方法和应用阶跃输入最佳响应准则的整定方法。通过仿真验证了上述算法的有效性和鲁棒性 ,且具有一定的工程实用价值。
In order to solve the problem of large delay in process control, Smith predictive control is introduced and the tuning method of the control system is introduced. Two kinds of pole configuration algorithms are given: tuning method based on ITAE criterion and setting of optimal response criterion method. The validity and robustness of the above algorithm are verified by simulation, and it has certain engineering practical value.
