Abstract: This paper addresses the issues of insufficient motor control precision and unstable driving performance of small single-seat electric off-road vehicles under complex road conditions by proposing a motor control strategy based on fuzzy proportional-integral-derivative (PID) control. By integrating fuzzy logic with traditional PID control and utilizing fuzzy rules to dynamically adjust PID parameters, precise control of motor speed and torque is achieved. Simulation and experimental results demonstrate that this control strategy effectively enhances the dynamic response performance during starting, acceleration, and hill-climbing conditions, while also improving the system's anti-interference capability and stability. Compared to traditional PID control, the proposed fuzzy PID control method shows significant improvements in both driving smoothness and energy efficiency, offering a new solution for motor control in small electric off-road vehicles.

摘要： 针对小型单座电动越野车在复杂路况下电机控制精度不足、驾驶性能不稳定的问题， 文章提出一种基于模糊比例-积分-微分（PID）控制的电机控制策略。通过将模糊控制与传统 PID 控制相结合，利用模糊规则动态调整 PID 参数，实现了电机转速和转矩的精确控制。仿 真与实验结果表明，该控制策略能够有效提升电动越野车在起步、加速和爬坡等工况下的动 态响应性能，同时改善了系统的抗干扰能力和稳定性。与传统 PID 控制相比，所提出的模糊 PID 控制方法在驾驶平顺性和能量效率方面均有显著提升，为小型电动越野车的电机控制提 供了新的解决方案。
