摘要
提出了Smith预估器的基本思想不仅能应用于线性时延系统，还可应用于非线性时延系统及非最小相位系统，并给出了在开关式温度控制、开关式液压位置控制及汽包锅炉水位控制上的应用实例。
This paper shows that the idea of Smith predictor can be used not only inlinear time-delay systems,but also in nonlinear time-delay systems and in nonminimum phase systems as well. Some examples in temperature on-off control,hydraulic on-off sevo system and water level control of boiler drum are given addi-tionally.
