摘要
电动车无刷直流电机是一种集机、电、磁为一体的多能量源系统。针对传统应用无刷直流电机数学建模方法具有复杂性的不足,在分析其物理模型的基础上,采用键合图方法对电机进行建模,并且根据简单的对应关系将键合图转化为方块图,然后在MATLAB/Simulink中进行动态仿真。建模过程与仿真结果表明,键合图结合方块图对于电机的建模与仿真具有一定的实用性和有效性。
Brushless DC motor for electric vehicle is a multiple energy system that includes machine, electric and magnetism. Aiming at the shortage that using traditional method of mathematical modeling for brushless DC motor has complexity, brushless DC motor with bond graph method is modeled based on analyzing its physical model, and changes the bond graph into block graph according to simple corresponding relationship. Then its dynamic performance is simulated in MATLAB/Simulink. The modeling process and simulation results show that bond graph combined with block graph possesses certain practicability and availability for modeling and simulation of brushless DC motor.
