Linearizing of electrimechanical system Simulink Model. How to do it ?

Hi there,

I have electromechanical system Simulink model, with the following components:

1-The mechanical subsystem equations represented by basic operators

2- The controller contains a look-up table, PID controllers and SVPWM.

3- PM synch. motor.

I am facing a problem of getting zero reference values because the PID controller doesn't linearize the system.

My background about linearization is really very basic, especially in Simulink environment! bucause of that, I couldn't fix the issue. What do you think the problem is? Is it in PID linearization? or any other setting in Simulink? I really need a guiding recommendation.

Regards

If you have a steady state operating point you can try this.
