摘　　要：为了提高ROV推进系统的运行性能,通常使用永磁同步电机作为推进电机。此外,无传感器的位置估计可提高推进电机的应用范围,估计结果可以代表机械传感器测量值的冗余性。论文提出高频注入算法与二阶广义积分器(SOGI)相结合。通过与转子位置直接相关的q轴电流的近似计算,准确地估计了位置和转子速度。此外,通过引入二阶广义积分器,有效地减少了估计位置的谐波。然后,在Matlab/Simulink中通过选择不同的低速实验验证来转子位置估计算法的可靠性。In order to improve the performance of ROV propulsion system,permanent magnet synchronous motor is usually used as the propulsion motor.In addition,sensorless position estimation can improve the application range of the propulsion motor,and the estimation results can represent the redundancy of the mechanical sensor measurement values.This paper proposes a high frequency injection algorithm combined with second-order generalized integrator(SOGI).Through the approximate calculation of the q-axis current directly related to the rotor position,the position and rotor speed are accurately estimated.In addition,the har⁃monic of the estimated position is effectively reduced by introducing a second-order generalized integrator.Then,the reliability of the rotor position estimation algorithm is verified by selecting different low-speed experiments in Matlab/Simulink.
