碩士 === 國立勤益科技大學 === 電機工程系 === 102 === This paper proposes the real-time XXY stage extension fault diagnosis based on master-slave chaotic error dynamics, the main characteristic signal is extracted by filtering from the microvibration of platform. The chaos synchronization system extracts the dynamical map of chaotic dynamic error. The eigenvalue is extracted from the centroid value of phase plane plot, and the value is analyzed by extension theory, so as to determine the state of XXY platform. The platform states can be detected by the PC based real-time analysis, there are four fault statuses, including normal, motor fault and collide fault. The dSPACE is used for signal acquisition and monitoring interface making, the real-time fault monitoring and diagnosis can be implemented at the computer side.
