考虑饱和效应凸极同步电动机矢量控制

摘要

By using the closed-loop compound flux-linkage observer, the excellent results of air gap flux-linkage observer can be obtained. On this basis,the mathematical model of salient-pole synchronous considering magnetic field saturation effect is proposed. On the experiment platform of synchronous motor with DSP2812 as the core, the vector control experiment of synchronous motor is completed.The experimental results show that the proposed air-gap flux field oriented vector control system has high dynamic and static characteristics. Furthermore,by using the saturation mathe-matical model established to analyse and control the synchronous motors while magnetic field is saturation and nonlin-earity, the synchronous motor speed control system has high dynamic response.%通过闭环复合磁链观测器,可获得优良的气隙磁链观测效果.基于此,提出一种考虑饱和效应的凸极电机数学模型,利用DSP2812为核心的同步电机实验平台,完成了同步电机矢量控制实验.实验结果表明,基于所提出的气隙磁场定向矢量控制系统具有高性能动静态特性,利用此处建立的饱和数学模型分析和控制同步电机,在磁场饱和非线性时,同步电机调速系统动态响应较快.
