摘要
为了满足电传动装甲车辆轮毂电机驱动系统大扭矩、高速度、快响应的需求,以大功率永磁同步轮毂电机为研究对象,采用最大转矩电流比及弱磁调速控制策略,根据电机实际运行状态生成电流查询表。结合基于转矩给定的磁场定向矢量控制思想和空间矢量脉宽调制(Space Vector Pulse Width Modulation,SVPWM)技术,对轮毂电机控制系统进行仿真分析。通过稳态和动态特性仿真试验,验证了所设计的控制系统能够更好地满足电机性能需求。相对于传统矢量控制系统,弱磁扩速能力强,而且系统响应速度快、转矩脉动小。
To meet the needs of large torque,high speed,fast response for the wheel motor drive system of electric drive armored vehicle,taking the high-power permanent magnet hub motor as the research object,using the maximum ratio of torque to current and the flux-weakening control strategy,a current query table is generated based on the actual running state of the motor. The simulation and analysis of motor control system are carried out by using the idea of magnetic field orientation vector control based on torque reference and Space Vector Pulse Width Modulation( SVPWM) technique. Through steady-state and dynamic characteristics simulation experiments,it is verified that the control strategy can meet the performance requirements of the motor well. The flux-weakening capability is high,the response speed is fast and the torque ripple is little for a given torque compared with the traditional vector control system.
