摘　　要：　如果Smith预估补偿器的预估模型和被控过程的模型不完全匹配,闭环控制系统稳定性不理想。本文采用可变死区范围的非线性方法改进基本的Smith预估补偿器,使得闭环系统关于模型不匹配的稳定鲁棒性令人满意。The closed loop control system will be unstable if the models of Smih precompensation controller and the process are not matched.To improve the Smith precompensation controller,a noninear method with varied dead zone is adopted in this paper,so the robust of stability about the unmatched models of the closed loop system is satisfying.
