Hi NXPtechnical team
I refer to the FOC control application of s912zvm(AN5135). The official scheme, rotor position / speed estimation uses BEMF observer. This principle has requirements on the speed, which is not applicable to the occasion of starting at very low speed with large load.
I need to be able to use the zero speed control scheme, whether the high-frequency injection method is used, and if the resources of s912zvm cannot be met, Can it be implemented on s32k series chips? I look forward to NXP's application in this regard.
Thank you
