用于扭矩控制系统的PMSM FOC lib从0rpm开始

你好，


我想询问STM PMSM FOC库在应用中的情况，在大多数情况下受控电机处于静止状态，从那时起它必须能够以可变扭矩（在方向和值方面）旋转。因此，如果我理解正确，我需要控制电机而不需要旋转序列。是否有可能通过FOC lib实现，或者我需要为这种情况制作我自己的控制算法。
计划系统将配备12V 2-4A PMSM电机，3个电流分流传感器和HALL探测器（最终应用HALL探测器应仅用于开始旋转）。

作为系统，要求：
1.电机从0rpm开始，始终由扭矩控制直至完全停止，
2.尽可能避免扭矩波动，
3.尽量减少电机噪音。

先谢谢你，

Hello,


I would like to inquire about STM PMSM FOC library use in case of application where controlled motor is in stand still in most cases and from that point it have to be able to spin at variable torque (in terms of direction and value). So if I understand correctly I would need to control motor without spin-up sequence. Is it possible too achieve that with FOC lib or do I need to make my own control algorithm for such case.
Planned system will have 12V 2-4A PMSM motor, 3 current shunt sensors and HALL detectors (for end application HALL detectors should be used only to start spinning).

As system it is required that:
1. Motor would start from 0rpm and always run controlled by torque until full stop,
2. Avoid torque ripples as much as possible,
3. Minimize motor noise.

Thank you in advance,
Laurynas
