摘要:
 摘要:针对开关磁阻电机(SRM)非线性建模中多变量输出累积误差问题,根据实测样机数据,采
用最小二乘支持向量机(LSSVM)方法,建立了非线性多输入多输出(MIMO ) SRM模型。与传统
LSSVM法SRM模型相比在结构上进行了改进,该模型中LSSVM的输入为角度、磁链,输出为电流、
转矩及磁链对角度的偏导,此多输入多输出LSSVM避免了以往多个单输出LSSVM组合造成的累
积误差。在SIMULINK中用S函数实现了LSSVM模型的仿真。实验结果表明,仿真电流波形和实
测电流波形一致,实测峰值电流42 A、峰值角度6. 36°及关断角电流29 A时,仿真的3个相应参数为
43. 5A,6. 58° ,29A,误差均较小,从而验证该文提出的建模方法的正确性和有效性。
Abstract:
 Abstract:A nonlinear multi-input multi-output(MIMO)model based on least squares support vector ma-
chine(LSSVM)was built according to the measured prototype characteristics,aiming at the problem of
accumulated errors with multi-variable output of nonlinear switched reluctance motor(SRM)model. An
improvement in structure was conducted compared with the traditional LSSVM modeling of SRM,and the
inputs of LSSVM are angle and flux,and,outputs are current,torque and flux partial derivatives of the
angle,what’s more,this multi-output LSSVM avoids the accumulated errors caused by the previous com-
bination of multi single-output LSSVM. The simulation of LSSVM model was complemented in Simulink
using S function. It has been shown by experiments that the current waveform obtained by simulation is
consistent with the experimental current waveform. When the peak current is 42A,peak angle is 6. 36°
and turn-off current is 29A in experiment,the corresponding simulation results are 43. 5A,6. 58° and
29 A,which verify the correctness and effectiveness of the proposed modeling method.
