基于DSP的无位置传感器无刷直流电机控制

DSP-Based DC Motor Control without Position Transducer and Brush

围绕无位置传感器无刷直流电机控制中的两个关键技术——位置检测和起动,提出了将瞬时状态检测和预测估计相结合的电机转子位置检测方法和“三段式”起动。

Focusing on two critical technologies -position detection and start up- in the control of DC motors without position transducers and brushes, the article put forth rotor position detection and three-step start up technologies that combines transient detection function with predicted estimate function.
