The power stage should respond to a setpoint change in desired voltage Vcmd in about 5
sampling periods with a peak error (across frequency) of 50%. Use a tracking
requirement to capture this objective.
Req1 = TuningGoal.Tracking('Vcmd','Vchip',5*Tm,0,1.5);
Req1.Name = 'Setpoint change';
viewGoal(Req1)
The power stage should also quickly reject load disturbances iLoad. Express this
requirement in terms of gain from iLoad to Vchip. This gain should be low at low
frequency for good disturbance rejection.
