    摘要:

    开关磁阻电机(Switched reluctance motor, SRM)因结构简单坚固、起动转矩大和转速范围宽的特点,在电动车驱动系统有着广阔的应用前景。不同于异步电机和同步电机依靠调节器双极性输出量实现四象限工作,传统单极性SRM转速环控制系统需要依靠外部给定来切换工作象限,在四象限运行工况下存在切换过程平滑性难以控制的问题。针对此,本文提出一种将SRM转速环控制系统及其四象限控制方法相结合,以传统的角度位置控制(Angle position control, APC)理论为基础,将转速调节器双极性输出量与电机转速方向进行逻辑判断形成新的APC控制参数,配合传统电流斩波控制(Chopping current control,CCC)形成新型的四象限转速环控制系统。该系统优化了SRM频繁电制动切换的顿挫问题,为电动车坡道动态行驶安全提供了平滑切换的保障。仿真和实验结果均验证了该系统原理的可行性,较好地实现了电动车SRM驱动系统的四象限工况切换。

    Abstract:

    Switched reluctance motor (SRM) has heralded considerable applications in electric vehicle drive systems, primarily due to its robust and simple construction, high starting torque, and broad speed range. Unlike asynchronous and synchronous motors that leverage the bipolar output of regulators for quadrant Ⅳ operation, traditional unipolar SRM speed loop control systems rely on external inputs to toggle operational quadrants, leading to challenges in ensuring smooth transition during such quadrant shifts. To address this issue, this paper introduces an integration of the SRM speed loop control system with its four-quadrant control approach. Based on the foundational theory of angle position control (APC), this paper logically associates the bipolar output of speed regulators with motor speed direction to form a novel APC control parameter. When combined with traditional chopping current control (CCC), it creates a new model for four-quadrant speed loop control systems. This system alleviates the jerkiness issues associated with frequent braking switches in SRMs, ensuring smooth transitions for electric vehicles during hill-climbing scenarios. Simulation and experimental results both affirm the feasibility of this system’s principle, and enhance the smoothness of quadrant transitions in electric vehicle SRM drive systems.
