The angle from the initial conditions IPMSM motor

How to simulate determining the angle from the initial conditions when the IPMSM motor is stationary using a power model?

Please refer to the following document page of IPMSM block.

You can define the initial values of Id Iq currents, angle and speed in the block mask.

Do you know the method they use in this?

Estimate Initial Rotor Position Using Pulsating High-Frequency and Dual-Pulse Methods - MATLAB & Simulink Example (mathworks.com)

To obtain data for a real motor and use this data to create a nonlinear motor model for simulation, how would you go about calculating it?

Thanks!!!

Yes, the method used in the example: Estimate Initial Rotor Position Using Pulsating High-Frequency and Dual-Pulse Methods - MATLAB & Simulink Example (mathworks.com) is a closed loop technique similar to phase locked loop. You may refer to the following page as well : https://in.mathworks.com/help/mcb/ref/pulsatinghighfreqobserver.html

About the second question, if you are refering to estimating motor parameters to create a nonlinear motor model for simulation then refer to following page:

Do you have any documentation or could you guide me on the techniques being used? I'm working on a project to determine the position from the data of a PMSM motor when it's stationary. Please help me. Thank you.
