采用单片机为主的数字控制是无刷直流电动机的主要控制手段，本课题采用单片机及C/汇编语言及模糊控制算法，主要实现无刷直流电机的换相控制、起动电流的限制、转速控制、正反转控制等功能。软件设计重点及难点主要在转速、电流闭环的控制算法及电子换相的实现等。

-Microcontroller-based digital control is the main means of control of the brushless DC motor, the subject of using a microcontroller and C/assembly language and fuzzy control algorithm, the main achievement of the brushless DC motor commutation control, the starting current limit, speed control, Reversible control and other functions. Software design focus and the main difficulties in the speed, the current closed-loop control algorithms and electronic commutation to achieve.
