外文摘要：Through the analysis of the inner magnetic dynamic process of electro-hydraulic proportional valve, this paper presents the sensorless detecting method based on "electro-reflection" to feed back the fault information directly. And the paper places emphasis on the study of typical inner characteristic parameter of electro-hydraulic slide valve influence on the detecting sensitivity and robustness. On the basis of research of theoretical model building for jam fault, the oscillation current waveform and frequency influence on the non-sensor detecting sensitivity and robustness was analyzed by simulation software SystemView. Simulation results demonstrate that oscillation current with sinusoid waveform and 50Hz frequency has a best performance in this sensorless detecting method.
