Due to the problems of high cost and poor flexibility in the development of brushless DC motor control system for sidewall coring. a dual-core brushless DC motor control system based on ARM and DSP was designed. The man-machine interaction and data communication can be realized by ARM controller. while the real-time control. analog sampling and data processing of the brushless motor can be realized by DSP controller. In this paper. the mathematical model of brushless DC motor was firstly established. and the overall design of the system as well as software and hardware design was completed. Finally. the experimental results show that the control system can operate stably and meet the requirements of brushless DC motor for control system. At the same time. the development cost has been reduced. which has engineering reference significance.
