摘要
为了提高鱼雷电机的效率和转矩密度,介绍了对转永磁同步电机的结构,探讨了对转永磁同步电机的直接转矩控制技术,推导了对转永磁同步电机的数学模型,建立了电机仿真模型,分析了电机设计原理。为了保持双转子的等速,设计了一种新型对转永磁同步电机的直接转矩控制系统,提出了电机扰动情况下的双转子转速跟随方案,并进行了仿真。仿真结果和理论分析吻合,证明了直接转矩控制技术可以很好地实现对转永磁同步电机的调速,且控制过程简单,转矩响应迅速,鲁棒性强。
To improve the torque density and efficiency of a torpedo motor, the configuration and working principle of a counter-rotating permanent magnet synchronous motor（PMSM） are introduced. A simulation model of counter-rotating PMSM is established by deducing its mathematical model, and the design principle of this kind of motor is analyzed. A new direct torque control system for counter-rotating PMSM is designed, and the speed following strategy of two rotors in disturbance condition is proposed to keep the speeds of two rotors equal. Simulation result, which coincides well with the theoretical analysis, verifies that direct torque control is competent for regulating speed of counter-rotating PMSM with high robustness and quick torque response.
