Simulink Control Design™ - MathWorks

For example, suppose you have a DC motor for which you want to tune a PID controller.

The response of the motor is modeled as G(s) = 1/(s + 1)^2. Create a fixed LTI model

representing the plant, and a tunable PID controller model.

Gmot = zpk([],[-1,-1],1);

Cmot = tunablePID('Cmot','PID');

Open Control System Tuner.

controlSystemTuner

Control System Tuner opens, set to tune this default architecture. Next, specify the values

of the blocks in the architecture. Click to open the Standard feedback

configuration dialog box.

Enter the values for C and G that you created. Control System Tuner reads these values

from the MATLAB workspace. Click OK.

The default value for the sensor dynamics is a fixed unity-gain transfer function. The

default value for the filter F is a tunable gain block.

You can now select blocks to tune, create tuning goals, and tune the control system.
