摘要
在伺服控制系统中,控制器对内置式永磁同步电机(IPMSM)的性能影响较大。采用时步有限元分析方法,通过在Maxwell中搭建IPMSM三维和二维瞬态电磁场有限元模型,在Simulink中搭建了电机控制算法的模型。经由Simplorer软件接口技术将有限元模型和电机控制算法模型相结合,构建了永磁同步电机的场路耦合仿真模型。分析了电机在不同控制策略和工况下的转矩、电流、损耗、弱磁调速范围等数据,为IPMSM伺服调速系统的计算及优化设计提供了合理的方法。
In the servo control system,the controller has a great influence on the performance of the interior permanent magnet synchronous motor(IPMSM).The time-stepping finite-element method is used to analyze the IPMSM.Both 3D and 2D transient electromagnetic field finite element models are built in Maxwell software.A model of motor control algorithm is built in Simulink software.The finite element models and motor control algorithm model are combined by Simplorer interface technology.The field-circuit coupling simulation model for IPMSM is built.The data of torque,current,loss and flux weakening speed range of the IPMSM under different control strategies and different working conditions are analyzed.It provides a reasonable method for the calculation and optimal design of the IPMSM servo speed control system.
