摘　　要：根据混杂系统建模思想,提出了一种采用有限状态机理论对无刷直流电机系统仿真分析的新方法。这种方法根据无刷直流电机主要控制电力开关管的导通和关断顺序以及开关管导通和关断时间的特点,将它的控制回路划分为不同的工作状态,并将这些工作状态组合成一个具体的有限状态机来实现。采用广泛使用的Simulink/Stateflow为仿真工具来实现对无刷直流电机的控制回路仿真。通过对三相无刷直流电机控制系统的仿真分析,论证了这种方法的正确性和有效性。A novel method simulating a brushless direct current（DC） motor was presented, based on principles of hybrid system modeling and finite state machine theory. Brushless DC motor control mainly focuses on controlling the on/off condition and power switch duration. Modes of control therefore can be defined by corresponding states, and the states can be combined as a finite state machine. This approach uses the popular Simulink/Stateflow simulation method to control brushless DC motor loops. A threephase brushless DC motor was analyzed to illustrate the process of model building with Simulink/ Stateflow. The analysis demonstrates the feasibility and validity of the proposed method.
