Closed loop control for multilevel inverter

hi

I am designing a three level diode clamped multilevel inverter for my academic project. The entire design has been carried out using mathematical model in simulink. I have also designed a low pass filter(LC).The load i have connected is a resistive load. The modulation index of the inverter should vary depending on varying load conditions. Can you please guide me as to how am i supposed to design a closed loop feedback control using a PID controller.

Thank you

You can use the PID Controller block in series with process variables and to make it in closed loop you can use the sensor block.

For SPWM drive, you can use the output of the controller to vary the magnitude of the sinewave that is being compared with the sawtooth waveform.
