Position Tracking Controlling System on Sensorless BLDCM by Using MRAC

摘要：

This paper is mainly about sensorless brushless DC motor (BLDCM) controlling system based on MRAC method, which substitutes the traditional controlling system, the problem of hall tracking err when running at low speed is solved. In addition, a new hall sample circuit is designed and analyzed. By the virtue of overcoming the disturbance of hall that causes the wrong actions of the controlling circuit, this method improves the stability and accuracy of the whole system. MRAC controlling arithmetic is applied, after the self-learning and revise process is finished, the mock hall singled can be used to replace hall sensor in the system, also experimental results is provided.
