模块化多单元永磁同步轮毂电机控制策略研究
摘 要
模块化多单元永磁同步轮毂电机作为电动汽车驱动系统的重要组成部分,具有结构紧凑、传动效率高和能量利用高效等优点,但其控制策略复杂且各单元间协调控制难度大。为解决上述问题并提升电机系统的整体性能,本文针对模块化多单元永磁同步轮毂电机展开控制策略研究。首先建立精确的数学模型,基于此提出一种融合模糊逻辑与自适应滑模控制的新型控制算法,该算法能够有效应对参数变化及外部扰动,确保各单元间的协同工作。通过仿真分析验证了所提控制策略的有效性,在不同工况下均表现出良好的动态响应特性和稳态精度,同时显著提高了系统的鲁棒性和可靠性。

ABSTRACT
As an important part of the electric vehicle drive system, the modular multi-unit permanent magnet synchronous hub motor has the advantages of compact structure, high transmission efficiency and efficient energy utilization, but its control strategy is complex and the coordinated control among various units is difficult. In order to solve the above problems and improve the overall performance of the motor system, this paper studies the control strategy of the modular multi-unit permanent magnet synchronous hub motor. First, an accurate mathematical model is established, and a new control algorithm integrating fuzzy logic and adaptive sliding mode control is proposed. The algorithm can effectively respond to parameter changes and external disturbances to ensure the cooperative work of each unit. The effectiveness of the proposed control strategy shows good dynamic response characteristics and steady-state accuracy under different working conditions, and significantly improves the robustness and reliability of the system.
