PID_Feedback_Induction_Motor_EV.mdl

I am doing a three phase inverter for induction motor control for a graduate class project. For this, PID is going to be used in a closed loop with a PWM generation unit. Moreover, I will take the error between the reference speed of the motor and the actual speed of motor. But I am unsure on how to design a PID with six pulse PWM generation for a three phase inverter. Can anyone help me? I have attached my screenshot of my partially built model of the circuitry using simpowersystems blocks which includes battery, universal bridge for three phase inverter, general induction motor model, PID controller block, and PWM generator. I have also attached the simulink model for this partially completed model as well.

I also am stuck on this question regarding my project, did you finally figure it out?

I figured it out using different approach using field oriented control. You can look at an example by typing in power_acdrive in the matlab command if you have simpowersystems. For more details, go to the page http://www.mathworks.com/help/physmod/sps/powersys/ug/building-your-own-drive.html
