Simulink Control Design™ - MathWorks

Graphically Analyze Results of Control System Tuning

Tune the Simulink® model, rct_engine_speed, to achieve a specified settling time. Use

loopview to graphically analyze the tuning results.

Open the model.

mdl = 'rct_engine_speed';

open_system(mdl);

Create an slTuner interface for the model and specify the PID Controller block to be

tuned.

st0 = slTuner(mdl,'PID Controller');

Specify a requirement to achieve a 2 second settling time for the Speed signal when

tracking the reference signal.

req = TuningGoal.Tracking('Ref','Speed',2);

Tune the PID Controller block.

addPoint(st0,'u')

control = 'u';

measurement = 'Speed';

wc = 1;

[st1,gam,info] = looptune(st0,control,measurement,wc);
