摘　　要：针对工业过程滞后对象控制的问题,深入分析了Smith预估原理,提出了一种改进的Smith预估控制器。并基于ITAE优化准则给出了改进Smith预估控制器的参数整定方法。仿真验证了这种改进后的预估控制器具有较快的响应速度,展示了其良好的抗干扰能力和鲁棒性。该预估控制器具有一定的工程实用推广价值。To the industrial time-delay process, the principle of Smith predictor is introduced and analyzed. The new structure, of a modified Smith predictor is given particularly, Based on the ITAE criteria, the tuning method of the modified Smith controller＇s parameters are introduced. The simulation results identified the simplicity and validity of the proposed controller, and it has an excellent robustness and disturbance rejection. The proposed controller has hopeful application prospect.
