低速FOC控制X nucleo-ihM07m1

嗨，


只是一点背景。我们做运动控制产品，需要平稳的低速到高速运动。我们还需要高扭矩，所有这些都适用于BLDC和PMSM电机。从我所做的研究看来，FOC控制可能是最好的选择。然而，在使用核-F302r8和teh bull运行7极电机和ST MC工作台获得上述开发板之后 - 低速控制确实非常无用 - 电机失速低于1500 RPM - 即使使用简单的梯形控制我也可以轻松实现使用大多数高速电机降至500 RPM。我试过从默认值调整PID回路 - 我在低速振荡方面得到了一些改进，但它仍然以相当高的速度停止。在此期间我会尝试其他电机，任何人都可以了解如何在不使用步进器的情况下获得真正平稳且非常慢的电机运动以及他们对St的FOC图书馆和低速控制的实践经验，这应该是FOC的主要优势。非常感谢，Imtiaz

Hi ,


Just a bit of background. We do motion control products and require smooth low speed to high speed motion. We also need high torque and all this lends itself to BLDC and PMSM motors. From the research Ive done it seems that FOC control may be the best bet. However after getting the dev board mentioned above with the nucleo -F302r8 and teh bull running 7 pole motor and the ST MC workbench - the low speed control is really  quite useless - the motor stalls below 1500 RPM - even with simple trapezoidal control I can easily go down to 500 RPM with most high speed motors. I have tried tuning the PID loop from default values - I get some improvement on low speed oscillations but it still stalls at quite  high speeds. I will try other motors in the meantime can anyone shed some light on how to get really smooth and really slow motor movement without using a stepper and their practical experience with St's FOC librarty and low speed control which is supposed to be the main advantage of FOC. Thanks a lot , Imtiaz
