摘要
永磁同步电机(PMSM)伺服系统的速度环和电流环具有非线性耦合特性,需要进行电流解耦控制。因此,根据矢量控制的原理实现了该系统的线性解耦。通过对永磁同步电机数学模型分析,建立基于Simulink伺服系统矢量控制仿真模型。仿真结果表明,建立的系统耦合模型具有良好速度控制特性,并对永磁同步伺服耦合系统设计具有指导价值。
It is necessary to conduct current decoupling control, because there is non-linear coupling in PMSM servo system with speed and current closed-loops. Therefore, according to the theory of vector control able to make the linear decoupling come true in PMSM servo system. Though analyzing the math model of the servo system, the simulation models are separately constructed under simulink. From the results of the simulation, the coupling model of servo system has a approved performance for the speed control, it is a guide for the design of SVPWM in PMSM servo system.
