I have built a plant with a PWM generator,PI controller and a set point. The plant function is derived from the system identification toolbox. I get the error for linearization,and I know it is because of PWM generator and I need to make a Frd system and use this one.I have trouble getting the system I/O ports, in order to linearize it. Here is a picture of my system. Can one please help me where should I put in/output ports and how to use PIDtune in my system?

You should be able to upload the model. If it does not upload, put it in a zip file, and upload it.
