| 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. |
