I'm trying to simulate a induction motor driven by VSI with sinusoidal PWM. I have a 3 phase induction motor model and a SPWM model but still need a controller.
Does anybody know where I can get a code for the open loop constant V/Hz control for SPWM ? More specifically, I'm looking for a open loop controller of which input is the desired speed (or fundamental frequecy of motor terminal voltage) and output is the frequency of the carrier wave and/or the magnitude ratio of the modulating and carrier wave. Whereas this would be the best one for me, but any type of open loop V/Hz controller for SPWM would be great.
Thanks.
