摘要

提出了一种无刷直流电机的无传感器场定向控制方法。采用滑模观测器估计相电流，在电流观测器之后，提出反电动势观测器估计转子的电位置和速度。反电动势无传感器操作适用于中高速。并与传统观测器和所提出的观测器进行了比较。通过数值仿真验证了所提出的滑模观测器在无刷直流电机无传感器场定向控制中的应用。

Sensorless Field Oriented Control of BLDC motor based on Sliding Mode Observer

This paper presents the sensorless field oriented control of a brushless direct current motor (BLDC). A sliding mode observer is used to estimate the phase currents, after the current observer, a back-EMF observer is proposed to estimate the electrical position and speed of the rotor. The back-EMF sensorless operation is intended for medium to high speed. A comparison with a conventional observer and the proposed observer is carried out. Numerical simulations are presented to validate the proposed sliding mode observer for the sensorless field oriented control of a BLDC motor.
