摘要
为了实现水下大功率和高效率电力推进,介绍了对转永磁同步推进电动机的结构和工作原理。推导了其数学模型和电磁关系,建立了该电机的M atlab仿真模型;研究了对转永磁同步推进电动机的矢量控制原理,建立了该电机的矢量控制系统,设计了双转子在推进器扰动下的转速跟随方案,并进行了仿真。仿真结果与理论分析相吻合,验证了模型的有效性,说明了矢量控制技术可以实现对转永磁同步推进电动机的调速。
The structure and operation principle of anti-rotary PMSM for propulsion were introduced to achieve electrical propulsion with high efficiency and high power. After mathematic models and electromagnetism relation being induced, a simulation model was built up. Speed following strategy of dual rotors on condition of propeller turbulence was designed, and the vector control system for anti-rotary PMSM was constructed and simulated with Matlab/Simulink software. The simulation results, which were coherent with theoretical analysis, indicate that vector control is competent for speed regulation for anti-rotary PMSM with dynamic response and accurate control.
