LAUNCHXL-F280039C: Simulink Sensorless FOC Motor Example for LAUNCHXL-F280039C and BOOSTXL-DRV8323RS

Part Number: LAUNCHXL-F280039C
Other Parts Discussed in Thread: BOOSTXL-DRV8323RS, C2000WARE, BOOSTXL-DRV8323RH

Tool/software:

I have purchased the following boards:

  • LAUNCHXL-F280039C
  • BOOSTXL-DRV8323RS

I am looking for a Simulink example for Sensorless FOC Motor control (the motors are actually BLDC, not PMSM).

I have found the example mcb_pmsm_foc_sensorless_f28069MLaunchPad.slx but this is for a different launchpad so does not build.

How can I get Sensorless FOC Motor control running on the boards I have using Simulink ?

    Referring to the mathworks help site, https://www.mathworks.com/help/ti-c2000/ug/sensorless-foc-example.html 

    The F28003x does not appear to have a built-in example project. However, the F28004x does. If you wish to implement your own, I would branch from the F28004x project and replace any relevant blocks as needed.

    Please note that e2e is unfortunately not a help forum for Simulink, and we are not guaranteed to be able to help you with any issues you may face. I will certainly try, though.

    Alternatively, the F28003x and BOOSTXL-DRV8323RS is a valid combination for the Universal Motor Control Lab via the C2000Ware Motor Control SDK. This is not in Simulink, but it is a functional example project.

    Thanks Jason

    I tried the F28004x example project and managed to get it to build and download.

    I then opened the host model to try and control the motor, but nothing happens.

    I've put the following post on the mathworks forum, any advice would be greatly appreciated...

    Also, which headers do I use to connect the BOOSTXL to the F280039C ?  Is the setup shown in the picture below correct ?


    I would also like to be able to use the TI InstaSPIN tool to charactertise the motor, is this possible with the example simulink models ? Or will InstaSPIN only work with CCS example code ?

    Unfortunately I do not know whether or not InstaSPIN is available by default in Simulink.

    For the connection, refer to the Universal Motor Control Lab User's Guide https://www.ti.com/lit/ug/spruj26a/spruj26a.pdf section 3.2.2 for LAUNCHXL-F280039C setup and section 3.2.9 for BOOSTXL-DRV8323RH setup.

    For the F28004x project, as I mentioned, I believe alterations will be required to get it to work with the F28003x, as that is a different core. I'm less familiar with the Simulink tool, so I do not know offhand what those alterations would necessarily be.
