Simulink Control Design™ - MathWorks

Finally, register the plant input as a site for open-loop analysis and use

TuningGoal.Margins to capture the stability margin requirement.

addPoint(ST0,'delta_m')

Req3 = TuningGoal.Margins('delta_m',7,45);

Autopilot Tuning

We are now ready to tune the autopilot parameters with systune. This command takes

the untuned configuration ST0 and the three design requirements and returns the tuned

version ST of ST0. All requirements are satisfied when the final value is less than one.

[ST,fSoft] = systune(ST0,[Req1 Req2 Req3]);
