摘　　要：针对主汽温被控对象的大迟延、大惯性、时变和非线性的动态特性,提出一种模糊控制和传统PID控制相结合的办法,既发挥了模糊控制对非线性或不确定性对象的良好控制作用,同时又保留了传统PID控制的优势,并且增加了控制器参数在线自动调整的功能,这样满足了多种工况下被控对象主汽温的自适应要求。通过MATLAB仿真平台的结果可以看出,利用该方法能获得较好的动态控制品质和精度。Based on the dynamic characteristic of main steam temperature： large delay,large inertia,time-varying,nonlinear,a kind of method combineing fuzzy control with traditional PID is proposed.It not only play the function of good control on nonlinear or uncertain object,but also retain superiority of raditional PID,and add the function of adjusting the controller parameters on line automatically,meeting the adaptive demands of main steam temperature in many conditions.By the results of MATLAB simulation platform,dynamic control of qualities and accuracy are gained.
