摘　　要：针对时滞对象,把Smith预估控制原理和模糊控制器结合起来,即在Smith预估控制系统中控制器采用模糊控制器.仿真结果表明,所采用的方法能有效克服普通模糊控制算法不适应时滞系统控制和常规Smith预估控制算法过分依赖模型精度的缺陷,提高普通模糊控制器对时滞系统的控制能力,同时该算法具有很强的鲁棒性和良好的控制品质.Aiming at the time-delay system, the Smith predictive control is combined with fuzzy control. In other words, controller uses fuzzy controller in the Smith predictive control system. Simulation shows that the presented method can effectively overcome limitations of common fuzzy control algorithm not fitting time-delay system and the general Smith algo- rithm depending on precision model excessively. At the same time, the Fuzzy-Smith control algorithm has strong robustness and better control performance.
