pid_mcm_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_mcm_tune(key1,key2,vars)  
key=0; Kp=[]; Ti=[]; Td=[]; lb=[];
K=vars(1); L=vars(2); T=vars(3);
switch key1
    case 1
        switch key2
            case 1
                Kp=K/3;Ti=L;
                key=1;
            case 6
                Kp=1.881*T/(K*L*(1+(T/(T+L))^0.65));Ti=1.66*L*(1+(T/(T+L))^0.65);
                key=1;
        end
