pid_wf_tune.m

很优良的PID控制器设计仿真程序与模型,经过严格检验

function [Kp,Ti,Td,key,lb]=pid_wf_tune(key1,key2,vars) 
key=0; Kp=[]; Ti=[]; Td=[]; lb=[];
K=vars(1); L=vars(2); T=vars(3); id=vars(4);   
switch key1
    case 1
        switch key2
            case 1
               x=[0.2 0.5 1.0 5.0];
               a0=[4.4 1.8 0.78 0.30];
               b0=[3.23 2.27 1.28 0.53];
               a=interp1(x,a0,L/T,'spline');
               b=interp1(x,b0,L/T,'spline');
               Kp=a*T/(K*L);Ti=b*L;
               key=1;
        end
