Simulate PMSM Drive with Thermal Model in DQ Frame

Since R2024b

This example shows how to simulate a permanent magnet synchronous machine (PMSM) in the direct-quadrature (DQ) reference frame. The PMSM contains a thermal model and empirical iron losses. To design the PMSM controller and achieve the desired performance, select the architecture and the gains for the model. The initial temperature of the stator and rotor is 25 degrees Celsius. The ambient temperature is 27 degrees Celsius. The Scopes subsystem contains scopes that allow you to see the simulation results.

This plot shows the requested and measured rotor speed for the test and the torque in the electric drive.

This plot shows the stator and rotor temperatures of the motor.

Results from Real-Time Simulation

This example has been tested on these platforms:

  • Speedgoat™ Performance real-time target machine with an Intel® 3.5 GHz i7 multi-core CPU and 4 GB RAM.

  • dSPACE® SCALEXIO LabBox with Intel® Core XEON E3-1275v3 at 3.5GHz and 4 GB RAM.

You can run this model in real time with a step size of 40 microseconds by using the Simscape local solver. For small sample rates, a task overrun might occur during the initial task execution due to a cold cache. To avoid this overrun, if the selected platform supports these options, relax the start-up behavior by specifying a limited number of task overruns or increasing the sample time of periodic tasks during the start-up phase of the real-time application.
