Research on Fault-Tolerant Control System of Brushless DC Motor Based on ARM
In view of the problems of over-voltage,under voltage,Hall sensor fault and lack of equality in the operation process of brushless DC motor control system,the hardware of brushless DC motor fault-tolerant control system is designed.The four fault types of power supply fault,power tube short-circuit damage fault,motor phase failure and Hall position detection fault are studied and analyzed,and the coping strategies are put forward,which are tested and verified on the test platform.Results show that the motor fault-tolerant system combined with fault response strategy has strong fault-tolerant performance,and can effectively improve the reliability of the motor system.
