摘要:
为有效预测永磁同步电机的温度,首先使用嵌套结构对门控循环单元(gated recurrent unit,GRU)进行改进,提出一种嵌套式门控循环单元(nested gated recurrent unit,NGRU)网络,NGRU能对相关温度特征中的噪声进行过滤,并挖掘温度随时间变化的规律,再经过非线性变换提取深层的温度特征; 然后提出一种新型深度学习模型,即一维卷积神经网络(1D convolutional neural networks,1D-CNN)串联NGRU(1D-CNN tandem NGRU,CNGRU),CNGRU利用1D-CNN对输入特征进行初步提取,得到多角度的永磁同步电机相关温度特征作为NGRU的输入,以串联的结构融合二者的优势,得到永磁同步电机的预测温度。试验结果表明,对比其他循环网络在定子轭、定子齿和定子绕组温度上的预测表现,NGRU均方误差平均降低12.44%,无穷范数平均降低0.361 9; CNGRU在此基础上比NGRU均方误差平均降低13.29%,无穷范数平均降低0.579 6。CNGRU比NGRU及其他循环网络对永磁同步电机温度的预测,具有更高的精度和稳定性,这为保证电机的安全稳定运行提供了技术保障。
