摘 要：針對(duì)雙邊型直線電機(jī)的氣隙偏心故障、繞組匝間短路故障，提出了一種基于雙邊型直線電機(jī)的故障信息融合診斷方法，該法通過(guò)數(shù)據(jù)層融合、特征層融合、決策層融合以及兩級(jí)診斷的方式來(lái)實(shí)現(xiàn)，其中數(shù)據(jù)層采用了Park矢量融合方法以及改進(jìn)的基8FFT算法，特征層采用了模糊人工神經(jīng)網(wǎng)絡(luò)法。將改進(jìn)的基8FFT算法、模糊人工神經(jīng)網(wǎng)絡(luò)法結(jié)合在一起，提高了雙邊型直線電機(jī)各種故障的診斷能力。
關(guān)鍵詞：雙邊型直線電機(jī)；故障信息融合診斷；改進(jìn)的基8FFT算法；蝶形單元；模糊人工神經(jīng)網(wǎng)絡(luò)

Abstract: Aiming at air gap eccentricity fault and winding turn-to-turn short circuit of bilateral linear motor, this paper proposed a kind of fusion diagnosis method of fault information based on bilateral linear motor. This method consisted of the data level fusion, feature level fusion, decision level fusion and the mode of two level diagnosis, of which the data layer adopted the Park vector fusion method and improved 8FFT algorithm, and the feature level adopted the fuzzy artificial neural network. The improved 8FFT algorithm was combined with the fuzzy artificial neural network to raise the diagnosis ability of various kinds of faults of bilateral linear motor.
Key words: bilateral linear motor; fault information fusion diagnoses; improved 8FFT algorithm; butterfly unit; fuzzy artificial neural network
