What is the formula to Auto Calculate Torque/Flux Kp & Ki (FOC motor brushless in Position Control) ?

Hi,

I don't understand the calculation for Auto Calculate Torque/Flux Kp & Ki in Motor Control WorkBench (Version: 6.0.0)

Could you send me the calculation formula because I can't find the same results. (I looked in your different documents and I can't find this equation).

I want to change these Kp/Ki because I have problems with some trajectories (overvoltage comes from PI Torque/Flux).

Best regards

um1052, ch. 4.10 describes how to determine the PI parameters for the torque/flux control loop.
