摘要
针对传统电驱动系统测试方案中存在的系统复杂、硬件成本高、灵活性低等问题,设计了一种参数化永磁同步电机(PMSM)模拟器。建立了PMSM的参数化模型,在此基础上进行了电机模拟器电力电子装置拓扑结构及控制策略的设计。通过MATLAB/Simulink平台进行系统仿真分析,验证了在不同工况及驱动器故障时利用电力电子装置模拟实际电机端口特性的可行性及有效性,为电机模拟器的应用奠定了基础。
Aiming at the problems of complex system,high hardware cost and low flexibility existing in the traditional test scheme of electric drive system,a parametric permanent magnet synchronous motor(PMSM)emulator is designed.The parametric model of PMSM is established.On this basis,the topology and control strategy of power electronic device of motor emulator are designed.The system simulation analysis is carried out on MATLAB/Simulink platform,which verifies the feasibility and effectiveness of using power electronic device to simulate the actual motor port characteristics under different working conditions and driver faults.This research lays a foundation for the application of motor emulator.
