Motor Control ACIM - TMS320Cxxxx and Stellaris

Other Parts Discussed in Thread: CONTROLSUITE

Hi ....

I´ve been looking for a Motor Control ACIM uC that has libraries for it. So TMS (Picollo and Delfino) and Stellaris are the choice.

But Stellaris has less resources than TMS.

  • Stellaris, control V/F; TMS, V/F and vector;
  • Stellaris PI control to Velocity ; TMS PID control velocity;
  • Both has sensorless;
So I think that TMS are best choice than Stellaris, what is your option about it? Does the Stellaris will be easier to start to work on? 
Some question that I didn´t find answer is the switching frequency of TMS libraries.
Best regards,
Brunomusw

    brunomusw,

    I am a bit partial to C2000 (TMS320xxxxxxx), but maybe that is because I work with the C2000 group. :)

    In my opinion, questions like these come down to:
    1) needs - What is your application specifications? What type of control do you expect to use in the end?
    2) experience - Have you worked with either before?

    If you will only do V/F control, Stellaris may be adequate and in fact a better choice for this application.  The C2000 will have more resources dedicated to running control loops and peripherals designed to drive MOSFETs/get sensor inputs & feedback from motors.  So if you're looking to experiment with things or do several things at a time, C2000 will likely fit better.

    If you end up leaning C2000, I would recommend downloading controlSUITE and taking a look at the HVMTRPFCKIT.  All documentation and software is provided for free in the controlSUITE download.

    The Stellaris forum would be the best place to find information on the Stellaris kit (RDK-ASIM).


    Thank you,
    Brett

    First, thanks Brett.

    1) I will enter in this world in a electric car, for fun, and after some experience I´ll go for product development, in the applications such pump and fun. Am I doing the opposite?  Pump and fun control is easier, don´t?

    2) Little, just an work in my master degree where I just build a 3 phase wave out in a 8 bit uC.

    Stellaris is cheaper than C2000, one point. ;)

    Can I adjust C2000 switching frequency?

    Regards,

    brunomusw,

    The C2000 software for ACI control is fully in controlSUITE.  You are allowed to change whatever you wish (you'll just have to confirm that whatever you change still makes the system work :) ).  I believe the default switching frequency in most of our example projects is 20kHz though.


    Thank you,
    Brett
