摘    要：论述SmiTH预估器的结构、模型精确时的SmiTH预估控制.针对时滞参数不确定时SmiTH预估器稳定性能变差,从理论上分析其原因,并提出采用专家方法实时调节控制参数,改善SmiTH预估控制的性能.仿真结果说明了本文提出的控制策略的有效性。

Abstract: In this paper,the structure of Smith predictive controller(SPC) and its control for cer-tain model are discussed. The reason why the stability of SPC is unsatisfactory when uneer-tain deadtime parameters occur in the model is analysed theoretically and the method of ex-pert adjusting control parameters online is presented, and the performance of SPC is modi-fied. The simulations have shown that the control strateges are effective.
