基于分形维数的PMSM局部退磁故障诊断
The Local Demagnetization Fault Diagnosis of PMSM Based on Fractal Dimension
摘要
Abstract
In order to achieve the local demagnetization fault diagnosis of permanent magnet in permanent magnet synchronous motor(PMSM),the mathematical model of PMSM is firstly set up with allowing for the local demagnetization fault of permanent magnet to implement the qualitative and quantitative electrical characteristics description of local demagnetization fault.Then,the local demagnetization fault diagnosis method is proposed,and the proposed method innovatively seamless integrates the adaptive fundamental wave extraction and the empirical mode decomposition(EMD),and then,the fractal dimension is calculated to achieve the fault diagnosis.At last,for the proposed method,both simulation and experimental tests are implemented in the stable and dynamic operation conditions of PMSM drive system to validate its feasibility and effectiveness关键词
