摘　　要：结合车辆轮毂直驱应用场合需求,以“低速大转矩”能力出色的轮辐式磁场调制永磁轮毂电机为研究对象,系统性开展以谐波为导向的电机转速波动抑制研究。分析齿槽转矩这一引起电机转矩波动的重要因素,确定与之相关联的主导谐波阶次。并且,将关联谐波作为优化设计目标,有效削弱齿槽转矩,从而有助于在电机设计层面实现电机转速波动的抑制。此外,面临轮毂直驱场合复杂工况及恶劣路况的驱动需求,在电机控制层引入“扰动抑制能力出色”的自抗扰控制技术,在自抗扰控制器误差反馈控制律中针对性引入电机齿槽转矩主导谐波的抑制环节,提出谐波导向型线性状态误差反馈控制律,进一步抑制了电机的转速波动。理论分析与实验结果验证了研究的合理性。Based on the requirements of vehicle hub direct drive applications,the spoke type permanent magnet hub motor with excellent“low speed and high torque”was taken as the research object,and sys-tematically the research of harmonic oriented motor speed fluctuation suppression was carried out.By an-alyzing the cogging torque,which is an important factor causing the motor torque fluctuation,the domi-nant harmonic order associated with it was determined.Moreover,taking related harmonics as the optimal design goal can effectively weaken the cogging torque,which is helpful to realize the suppression of motor speed fluctuation at the motor design level.In addition,in the face of the drive demand of complex work-ing conditions and bad road conditions in wheel hub direct drive,the active disturbance rejection control technology with“excellent disturbance suppression ability”was introduced into the motor control layer.The harmonic oriented linear state error feedback control law was proposed by introducing the harmonic-dominated harmonic suppression of motor cogging torque into the error feedback control law of the active disturbance rejection controller.The motor speed fluctuation was further inhibited.Theoretical analysis and experimental results verify the rationality of the study.
