Simulink Control Design™ - MathWorks

Validation

First validate the design in the linear domain using the slTuner interface. Plot the

closed-loop response to a step command Vcmd and a step disturbance iLoad.

figure('Position',[100,100,560,500])

subplot(2,1,1)

step(getIOTransfer(ST,'Vcmd','Vchip'),20*Tm)

title('Response to step command in voltage')

subplot(2,1,2)

step(getIOTransfer(ST,'iLoad','Vchip'),20*Tm)

title('Rejection of step disturbance in load current')
