    Serhii,

    I don't believe we have the Park Clarke transformations already implemented in our examples offering. 

    You could try the TMU based approach and IQ conversion, as I would expect this to be faster than an FPU only approach.

    Thanks,

    Sira

    It turns out the ControlSUITE and MotorControl SDK do have Park Clarke examples, depending on which device you're using.

    C:\ti\controlSUITE\libs\app_libs\motor_control\math_blocks\v4.3

    C:\ti\c2000\C2000Ware_MotorControl_SDK_2_00_00_00\libraries\transforms

    For your purposes, the MotorControl SDK should work.
