pid_lee_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_lee_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 5
                Ti=T+L^2/(2.666*L);Kp=Ti/(1.333*K*L);
                key=1;
        end
    case 2
        switch key2
            case 5
                Ti=T+3*L^2/(8*L);Kp=3*Ti/(4*K*L);Td=3*L^2*(1-L/(3*Ti))/(8*L);
                key=1;
        end
