本文提出并实现了具有仿人智能多模态控制算法的控制器．该控制器将模糊逻辑方法运用到PID参数自整定算法中，将改进型Z－N方法与模糊整定方法相结合，在线整定PID参数，用于由模糊控制、Bang－Bang控制、自整定PID控制三种控制模式相结合的多模态智能控制中，各控制算法间的相互切换采用专家系统进行监控、调度大量的数字仿真、模-数混合仿真运行结果表明，该控制器具有良好的鲁棒性和动、静态性能指标。

In this paper, a self-tuning-multiode intelligent controller is proposed, this new controller is extensively and thoroughly studied through digital and analog-digital hybrid simulation. The fuzzy logic algorithm is applied to self-runing of PID parameters, the modified Z-N method is combined to fuzzy self-tuning and the PID parameters is tuning on line. The classical PID controller is replaced by multimode intelligent controller which consists of fuzzy controller, Bang-Bang conrtoller and PID controller This multimode controller make the system have excellent dynamic and steady index. The result of digital simulation and hybrid simulation illustrate the controller is robust and effective.
