摘　　要：永磁同步电动机由于其优良的性能成为电力推进舰艇电机的最佳选择,为提高传统永磁同步电动机矢量控制策略中电磁转矩、电流、转速响应性能以适应复杂多变的海上工况,提出了一种具有复合转矩环的永磁同步电动机嵌模糊矢量控制策略,引入前馈复合转矩环提高系统抗负载扰动能力,采用嵌模糊控制取代传统PI速度控制增强系统鲁棒性和自适应性.利用MATLAB/Simulink搭建仿真模型进行针对不同优化程度的对比实验,验证了该控制策略的可行性和优越性.Due to the excellent performance of the permanent magnet synchronous motor,it has become the best choice of electric propulsion ship motor.In order to improve the response performance of electromagnetic torque,current and speed in the traditional vector control strategy of permanent magnet synchronous motor,and to adapt to complex and changeable marine conditions,a permanent magnet synchronous motor embedded fuzzy vector control strategy with compound torque loop is proposed.The compound torque loop is introduced to improve the anti-load disturbance ability of the system,and the embedded fuzzy control is used to replace the traditional PI speed control to enhance the robustness and adaptability of the system.The simulation model is built by Matlab/Simulink,and the comparative experiments for different optimization degrees are carried out to verify the feasibility and superiority of the control strategy.
