@inproceedings { , title = {Analysis and design of position and velocity estimation scheme for PM servo motor drive with binary Hall sensors}, abstract = {With the increasing demand of low-cost, high-efficiency, high performance for AC motor drive system, the permanent-magnet synchronous motor (PMSM) with binary Hall sensors begins to be adopted in many fields. Compared with sensorless control, the usage of binary Hall sensors is a guarantee for the drive to achieve moderate control performance, and it is in smaller volume and more cost-effective compared with other types of position sensors. In this paper, a solution is provided to realize fully-closed loop control with low-resolution position sensors, by treating the position and speed estimators as separate systems. Results reveal that the model-based methods can take advantage of model information and model-free methods can smoothly process the quantized Hall position signal. Extensive experiment results are provided demonstrating the position control performance and basic servo performance for a PMSM drive using 3 bit-per-pole-pair sensing system.}, conference = {2018 IEEE Energy Conversion Congress and Exposition (ECCE)}, doi = {10.1109/ECCE.2018.8558123}, isbn = {9781479973132}, note = {No embargo.
