mcb_pmsm_foc_sensorless_f28027LaunchPad Why is the default pi of the model so significant? I directly used the pi parameters set by the hardware, burned them directly, and found that the speed fluctuation was large through PMSM FOC Host control. Do you have a detailed introduction to this model? Just started1 个评论

Hello,
In all the demo examples, the PI controller parameters are calculated to achieve a specific control objective. This process requires knowledge of the motor parameters (such as resistance, inductance, inertia, etc.) as well as system parameters (like sampling delay, filter coefficients, and so on). As a result, the PI controller parameters will need to be adjusted if any of the motor or system parameters change.
I’d like to ask a clarifying question: When you used the PI controller parameters mentioned in your question, did you ensure that your motor and system parameters matched those used in the example?
