This paper presents a new method of expert controller, which is gotten by means of combining the technique of expert system with predictor control. The method adopts the multimode control as well as on-line characteristic identification so that the controller could not only give full play to the expert' s experience but also reflect the accuracy of predictor algorithm in control process. The simulation shows that the method has strong Robustness and good adaptability even when the object varies or the load changes suddenly, or something unexpected happenes with the system.
