Position control , "STM32 Motor Control"

[KKuma.3]

I am using Nucleo F303 RE and X-Nucleo - IHM08M1, MCSDK 5.4.4.

70 Watt motor with encoder.

I am able to control the position of the motor with the provided application for a limited speed.

Below are my questions,

1 how can I tune the motor for a better torque performance , for position control application?

2 I wanted to spin the motor at very low speeds, i.e position control at low speeds and higher torque.

The PID tuning explained in AN5464 is not sufficient and fails repeatedly@stm32.

3 I also wanted to know the impact of using the MCI_SetCurrentReferences api instead of MCI_ExecSpeedRamp or MCI_ExecTorqueRamp ?

4 How do I select the values of current if I use MCI_SetCurrentReferences api in MCboot for a particular motor ?

Dear @KKuma.3​ 

Sorry for the late answer.

Do you have still this problem to solve?

And just in case, if not, do not hesitate to share the final solution you found. Thanks by advance.

Yes I still have this issue.

I am unable to find the solution for the issues.

The question has been moved from the "Motor Control Hardware" section to the "STM32 Motor Control" section (the question is about the STM32 MC SDK).
