Research of SRM's Current Regulator Parameter Changed Based on Nonlinear Model

从实测数据数据出发,分析了SRM的非线性模型及其变化特点,得出了采用变参数电流调节器的必要性。提出了变参数电流调节器的设计方案,并且应用Matlab进行仿真。仿真验证了设计方案的可行性,并且最终应用于实验样机。将测得的电流波形与基于线性模型的电流调节器控制下的电流波形比较,采用本文的控制方案测得的电流波形超调量小,转矩脉动小,控制效果良好。

Based on the measured data, searched, and the necessary of current nonlinear modal and changed characteristics of SRM was reregulator parameter changed was proposed. current regulator was proposed. Furthermore, the simulation model of the system built, and the simulation results proved that the Design scheme of using Matlab was design scheme was viable. Compared with the current waveform of current regulator parameter unchanged based on linear modal, sant of current waveform which using current regulator parameter changed the overshoot and torque pulcontrol scheme were smaller. The control effect was preponderance obviously.
