Import the frequency data into PID tuner to allow the gains to be automatically tuned for
the outer loop. You can switch the supply to the AC source to test against the original
setup. The gains are fine-tuned with the crossover frequency chosen so that the controller
can follow the output voltage but reject the 120Hz oscillations of the voltage output. Set
the bandwidth to 342.5 rad/sec and the phase margin to 60 degrees to meet this
requirement.7 PID Controller Tuning
