LAUNCHXL-F28379D: FCL_379XL project current controller

Hello everyone,

I am trying to do level 3 for the FCL_379XL project. I completed level 1 and level 2 successfully. However, I have a problem controlling Id and Iq current value. My hardware is LAUNCHXL-F28379D, 2 DRV8305EVM, and TI 2Mtr dyno set's Teknic motors. I think the motor parameters were entered in the code and ı didn't change them. I just changed the drv gain from 40 to 10 and SINGLE_SAMPLING. I settled Id and Iq values as  0.05, but their values reach just 0.02-0.03. There is a steady-state error. I tuned the bandwidth, but it didn't work. How can I tune the KP Ki values for the current loop? I dınt find the Kp  Kp definition or calculation function. Do you have any suggestions? Could you help me?
