Could someone please guide me on the logic of writing this program? Especially how to connect the duty cycle after sampling the output voltage and current signals for PID control?

See the examples in the control suite

Can you tell me which one it is? I happen to have controlsuite on my computer

How to connect the duty cycle after sampling the output voltage and current signals for PID control? First, you need to model the inverter, calculate the transfer function of the duty cycle D, and then design a compensator for it. Using the PID algorithm, you can calculate the transfer function of the compensated duty cycle D, and then control the output duty cycle D according to the sampling results.
