基于改进有限位置集观测器的内置式永磁同步电机低速无传感器控制

This article proposes a finite position set observer based on a mathematical model considering cross-coupling factors for sensorless control of interior permanent magnet synchronous motors at low speeds. The objective is to address the limitations of conventional high-frequency (HF) signal injection methods, which suffer from reduced accuracy and practical implementation challenges in rotor positi...
