PID controller for vector control

Hello,

I am using TI's reference code to do vector control but the system's dynamic reponse is not satisfying.

Due to three contorl loops in the system,does anyone konw how to use matlab to derive the propotional,integral and correction gain for vector control.

I would be very thankful if any links or reference would be provided.

Thanks![***]

    Hi,

    my  PID controller tuning step(use mathworks simulink):

    1.       i use  ac6_example.mdl(PMSM) and ac7_example.mdl(BLDC)

    2.       ac7_example.mdl(BLDC) have PI gain calculator, I use calculator to get PID(gain value).

     

    Testing them in  simulink-simulation  is  working fine.

    So, I put the TI PID block in ac6_example.mdl(PMSM). Why the result cannot match? And I carefully calculate scaling factor, but the result cannot match.Should I believe which one is right?

    any idea to correct this difference?

    Do you have any mathworks simulink model to get PID(gain value)?Best Regards
