pid_cc_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_cc_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=(0.9*T/L+0.083)/K;Ti=T*(3.33*L/T+0.31*(L/T)^2)/(1+2.22*L/T);
                key=1;
        end
    case 2
        switch key2
            case 1
                Kp=(1.35*T/L+0.25)/K;Ti=T*(2.5*L/T+0.46*(L/T)^2)/(1+0.61*L/T);Td=0.37*L/(1+0.2*L/T);
                key=1;
    end
