| Abstract: | The overall design idea of fault prognostics system for hydraulic components in missile launcher was presented. The monitoring target is determined, and then fault characteristic signal was selected, and finally fault characteristic parameter was abstracted from fault characteristic signal. The system hardware and software platform are respectively DAQ system and LabVIEW 8.0. Fault prognostics for hydraulic components in launcher were carried out by adopting support vector machine. |

| Keywords: | hydraulic component fault prognostic DAQ system support vector machine |
