STM32G431 Custom Control Board Noisy Current Sense

[TS-LMG]

Hello. 

I have developed a custom control board utilizing similar architecture to that of the STM-B-G431B ESC board. I am experiencing difficulties trying to tune the PI coefficients for current Iq and Id. The output plot from the motor pilot looks really noisy. I tried playing around with the coefficients, but I can't seem to stabilize the current readings. Could there be something wrong with my project configuration in the motor control workbench? Im using the YAGEO - PS0306FRL7W0R003L as my current sense resistor.

Hello @TS-LMG ,

" board utilizing similar architecture to that of the STM-B-G431B ESC board" could mean a lot of things!

Did you succeed to spin your motor with an G431 ESC board before developing your own board ?

Which version of the MCSDK do you use ?

Did you describe your board, or did you reuse G431 ESC board as it is?

Have you tried to spin your motor in open loop? did it spin? If yes, what do the currents look like ?
