摘要: 为提高电传动装甲车辆驱动系统的可靠性,研究车辆轮毂电机无位置传感器复合控制技术,并对速度过渡区间的切换方法进行了改进。建立了基于转矩、电流双闭环的永磁同步电机控制系统,基速上、下分别采用弱磁控制和最大转矩电流比控制策略;电机低速区采用简化的脉振高频注入法,中、高速区采用模型参考自适应法,以实现全速度范围内转子位置辨识;采用变权重加权控制切换方法,并改进算法切换过程中两种算法工作区间的选择,在保证辨识精度的同时节省了系统的软、硬件资源。仿真和试验结果表明:无位置传感器复合控制算法能够在全速度范围内准确辨识出转速和转子位置;改进后的切换方法能够保证电机在速度切换区间内实现平滑过渡,保证了电机可靠运行。

Abstract: The compound position sensorless control technology of hub motor is studied, and the switching method of the speed transition interval is improved to increase the reliability of drive system in electric drive armored vehicle. A permanent magnet synchronous motor (PMSM)control system based on double closed loops of torque and current was built, for which the maximum torque per ampere (MTPA)control below the base speed and the flux-weakening control above the base speed are used. A simplified high frequency pulse injection method is used at low speed, and a model reference adaptive system (MRAS) is used at medium and high speeds to realize the rotor position identification in the full speed range. The variable weight weighted control switching method is adopted, and the working interval selection of the two algorithms is improved in the process of algorithm switching. The system hardware and software resources are greatly saved while assuring the identification accuracy. The simulated and experimental results show that the proposed sensorless algorithm can identify the speed and rotor position accurately in the full speed range, and the new switching method enables the motor to achieve smooth transition in the speed switch interval and ensures the reliable operation of motor.
