摘　　要：受海浪干扰因素影响,螺旋桨负载扰动造成的转矩波动直接影响水下推进电机的振动,进而影响水下噪声。为了降低水下推进永磁同步电机的振动和噪声,在分析螺旋桨负载扰动特性基础上,提出了自抗扰减振控制方法。该方法以自抗扰控制器替代电流环的传统PI调节器,对螺旋桨负载扰动进行观测并对转矩电流进行补偿,可有效抑制相电流谐波进而降低电磁转矩波动。仿真结果验证了该方法的有效性。Under the influence of wave disturbance,the torque fluctuation caused by propeller load disturbance directly affects the vibration of underwater propulsion motor,and then affects the underwater noise.In order to reduce the vibration and noise of underwater propulsion permanent magnet synchronous motor(PMSM),the active disturbance rejection control(ADRC) for vibration reduction is proposed based on the analysis of propeller load disturbance characteristics.Phase current harmonics and electromagnetic torque fluctuation can be effectively reduced by using ADRC instead of traditional PI regulator in the current loop,and the propeller load disturbance can be observed and the torque current can be compensated.The simulation results show the effectiveness of the proposed method.
