摘　　要：为提高全电化军用特种车辆的可靠性,进一步提升车载发电系统的功率密度,提出一种全速度范围内的永磁同步发电机无位置传感器控制策略。发电系统采用电压、电流双闭环的矢量控制算法,根据转速划分工作区,在低速区内,通过基于正交锁相环的角度跟踪器获取转子位置信息,在中高速工作区内,基于线性状态观测器实现转子位置估算,并结合基于递推最小二乘法的参数辨识算法,向观测器实时更新不同工况下的电机参数,以保证无位置算法的鲁棒性。仿真和实验结果表明:该控制策略在全速度范围内皆能实现精准的转子位置观测,电机状态在工作区切换处过渡平滑,负载投切时系统响应快速稳定,保证了特种车辆发电系统运行的可靠性。To improve the reliability of electric military special vehicles and further increase the power density of the on-board power generation system, a sensorless control strategy using a permanent magnet synchronous generator in the full speed range is proposed. The power generation system adopts a double-closed loop vector control algorithm for the voltage and current, and the working area is divided according to the rotational speed. In the low-speed area, information of the rotor position is obtained through the angle-tracking controller based on the quadrature phase locked loop. In the medium-and high-speed work area, the rotor position is obtained through the linear state observer, and the motor parameters identified by the recursive least square algorithm are used to improve the robustness of position predictions. The simulation and experimental results show that the control strategy can achieve accurate rotor position observation in the full speed range;the motor state transitions smoothly as the work area switches;the system responds quickly and stably when the load is switched on and off, ensuring the reliability of the power generation system of special vehicles.
