LAUNCHXL-F280049C: Dynamic decoupling of current (Id and Iq) PI controller and Speed pole of FAST estimator

Hi

Based on my understanding and experience, dynamic decoupling of the current controller in FOC algorithm improves the performance of the system. I think it has not been implemented in the function PI_run_series() since it is the same function used for speed and current controller.

1. Does this dynamic decoupling implemented anywhere in the MotorControl SDK? If not and we were to implement by ourselves, would there be any implications of that anywhere?

2. Is default Speed Pole (USER_SPEED_POLE_rps = 100) based on FAST design and calculation and stays the same for all type of the systems?

 

Best,

Amit

    1. Unfortunately, no. You need to add a function to implement it and set the value to the argument "ffwdValue" of PI_run_series().

    2. Right. In most cases, it doesn't need to change.
