Abstract
This paper delves into high-speed motors'sensorless control,emphasizing their essential characteristics of high fundamental frequency and low inductance.It focuses on three key links of modeling,driving,and control,addressing challenges such as mathematical model coupling,low carrier ratio,and high stator current harmonics.The principles and research status of high-speed motors'sensorless control are summarized in the paper,covering precise modeling and decoupling control,driver topology,and sensorless control algorithms,especially the position estimation and compensation methods.The paper discusses the difficulties and challenges of high-speed motors sensorless control,including harmonic suppression,operational reliability,and high-performance full-speed range algorithms,and forecasts future development directions.
