Hi,

I have a school project where I need to design robust speed controller with load torque observer in simulink. In the simulation I'm using ramp current control and PWM on 3 phase PMSM. I have been trying to do it for a week now and don't know how to do it correctly.

Thank you for your help.

This paper may give you some hints. It refers to a Luenberger observer.

You can find a block for a Luenberger observer here
