摘要
讨论了永磁同步电动机的数学模型，在机电作动器推动负载做摆动运行的情况下分析了影响机电作动器动态性能的主要因素．利用电压极限曲线、电流极限曲线定量分析了气隙磁链、交轴电感对系统性能的影响，结合机电作动器动态指标要求，在理论分析的基础上结合计算得到的电机参数搭建系统仿真模型。仿真及实验结果表明系统能够满足动态指标。
The paper discusses the mathematical model of Permanent Magnet Synchronous Motor, analysis the main influence factors for dynamic performance in the situation of the Electro Mechanical Actuator promotes load swing, and analysis the effects of flux induced by magnets, pay axis inductance on the performance of the system using voltage limit curve, the current limit curve quantitatively. Finally the paper builds simulation model in combination with the dynamic performance requirements and theory analyses. The results of simulation and test show that the system can satisfy dynamic performance.
