基于S变换和PSO-LSSVM的永磁同步直线电机局部退磁故障识别

This article focuses on the local demagnetization fault recognition research of permanent magnet synchronous linear motor (PMSLM) and realizes the accurate identification of the position and degree of demagnetized permanent magnets. A fault recognition system based on S-transform (ST) and particle swarm optimization-least squares support vector machine (PSO-LSSVM) is proposed. The ST makes the ind...
