PWM Transfer function for an Inverter control system

Dear Matlab/Simulink User, I have been trying to simulate a inverter control system in Simulink and matlab, i have used a PID as my feed back control and an simple LC filter as the output of the inverter. i have got a decent open and closed loop characteristics, but i feel i have left out a very important parameter in the loop(PWM).Is there any good approximation of a PWM transfers function which i can use as a part of inverter control system. Thanks, S.Bharath

You can model the actual PWM, look for more details on our PWM page .
