PID调节

% PID Example

clear all
clc
num=[1];
den=[1 3 1];

Gp=tf(num,den);
H=[1];

M=feedback(Gp,H);
step(M);
hold on;

%%可以通过右键"递增值和运行节"来增加变量的值
Kp=26.33314
Ki=1
Kd=8

Gc=pid(Kp,Ki,Kd);
Mc=feedback(Gc*Gp,H)
step(Mc)
grid on

Kp =

   26.3331


Ki =

     1


Kd =

     8


Mc =
 
     8 s^2 + 26.33 s + 1
  --------------------------
  s^3 + 11 s^2 + 27.33 s + 1
 
Continuous-time transfer function.
