摘　　要：混合励磁同步电动机保持了永磁同步电动机低速大转矩的优点,同时通过调节励磁电流又可实现宽范围的高速弱磁运行。针对一种混合磁极式的混合励磁同步电动机,推导了其数学模型。根据有限元计算结果和数学模型,提出了适用于该混合励磁同步电动机低速运行时的最大转矩电流比控制策略,以及高速运行时功率因数为1的控制策略。借助MATLAB/Simulink软件,建立了混合励磁同步电动机控制系统仿真模型,针对其低速运行和高速运行进行了仿真计算,仿真结果验证了控制策略的正确性。The hybrid excitation synchronous motor maintains the advantages of the low speed and large torque of the permanent magnet synchronous motor, and at the same time, a wide range of high speed field weakening operation can be realized by adjusting the excitation current. A mathematical model of a hybrid magnetic hybrid hybrid excitation synchronous motor is deduced. According to the finite element calculation results and mathematical model, the maximum torque-to-current ratio control strategy suitable for the hybrid excitation synchronous motor at low speed operation and the control strategy with power factor 1 at high speed are proposed. With the help of MATLAB/Simulink software, the simulation model of the hybrid excitation synchronous motor control system is established. The simulation calculation is carried out for its low speed operation and high speed operation. The simulation results verify the correctness of the control strategy.
