LAUNCHXL-F28379D: C2000 MOTORCONTROL porting issues

Hi Ben,

Could you share the link of the thread you mentioned?

What estimator are they using? FAST or eSMO? How did they test the estimator? 

Thanks,

Jiaxin

Hi Jiaxin,

Hi Ben,

Okay, I see. Thank you. Was customer running with their own motor? Can they confirm their motor parameters are accurate?

There is another finding that you mentioned in a previous thread that you have to change the "obj->oneOverDcBus_invV" from the estimator output to ADC feedback in level 2 for the motor to operate, but level 2 always uses the actual ADC data as shown below.

To debug the estimator, it would be better to make sure the estimator functions well in level 2 when the motor is running in open loop control. 

Thanks,

Jiaxin

HI Jiaxin,

Sorry for the late reply.

At present, the motor used is a motor from Tongchuan, and under the level 2 construction, the display estimate has always been 31415.9277

Best Regards,

Hi Ben,

No worry. Since customer is using a custom motor, can they confirm the motor parameters defined in "user_mtr.h" are accurate? If they are not sure about these, they can run the motor identification first.

Thanks,

Jiaxin
