基于改进的转矩分配函数法的SRM转矩间接控制
|
摘要
针对开关磁阻电机转矩脉动大的问题,基于转矩分配函数法,介绍了开关磁阻电机的转矩间接控制方法及其数学模型。在转矩闭环中,引入交叉反馈以改善系统结构,并在此基础上,采用MATLAB/Simulink进行了开关磁阻电机转矩间接控制系统的转矩脉动抑制仿真研究。仿真结果表明,通过设计并改进的转矩分配函数,合理分配转矩,并且由转矩逆模型得到期望电流,以实现实时电流跟踪,能有效地抑制开关磁阻电机的转矩脉动,而且解决了一般转矩分配函数在线学习能力差的问题。
Based on the torque sharing function( TSF),the method of indirect torque control and mathematical models for switched reluctance motor( SRM) were introduced to solve the problem of torque ripple,in addition,cross feedback was introduced to improve the structure of the proposed system. And then,the simulation research of torque ripple minimization for SRM based on indirect torque control system was completed by MATLAB / Simulink software.Simulation results showed that torque of each phase could be shared reasonably by TSF,and that reference current could be achieved by torque inverse model,which could keep real-time tracking of current and effectively suppress torque ripple of SRM,but also has improved the ability of online learning for TSF.
