Abstract

Switched reluctance motor (SRM) has been widely developed in the field of new energy vehicles and home electrical appliances due to its advantages of simple structure, high fault tolerance, high reliability, good suitableness for harsh working conditions, and flexible control. This paper takes the switched reluctance motor used in electric vehicles as the research object. The simulation model of the system is established combined with the characteristics of the switched reluctance motor and the mechanical motion equation. Aiming at the problem that fuzzy control is easy to produce steady state error, a speed regulator of switched reluctance motor is designed based on fuzzy + integral control strategy. It is verified that the system has better dynamic response and steady-state performance after using the fuzzy + integral composite control strategy. Finally, a four-phase 16/12 switched reluctance motor used for EV is tested. The results show that the combined control strategy can effectively adjust the speed and torque of the motor, which verifies that the motor system has high robustness under different working conditions.

电动汽车开关磁阻电机的模糊加积分复合控制策略

开关磁阻电机(SRM)以其结构简单、容错能力强、可靠性高、适合恶劣工况、控制灵活等优点，在新能源汽车和家电领域得到了广泛的发展。本文以电动汽车用开关磁阻电机为研究对象。结合开关磁阻电机的特性和机械运动方程，建立了系统的仿真模型。针对模糊控制容易产生稳态误差的问题，设计了一种基于模糊+积分控制策略的开关磁阻电机调速器。结果表明，采用模糊+积分复合控制策略后，系统具有较好的动态响应和稳态性能。最后，对用于电动汽车的四相16/12开关磁阻电机进行了测试。结果表明，该组合控制策略可以有效地调节电机的转速和转矩，验证了电机系统在不同工况下具有较高的鲁棒性。
