METHOD FOR MONITORING AND DIAGNOSING PERIODIC VIBRATING PHENOMENON

摘要

PROBLEM TO BE SOLVED: To provide a method for monitoring and diagnosing periodic vibration phenomenon in which remodeling of phase matching hardware is not required at the time of comparing measured values with reference data obtained from the vibration model of a neural network constructed by learning teacher data prepared from limited measured data, by using reference data which are used at the time of diagnosing vibration data as the vibration model by stabilizing the vibration model. ;SOLUTION: In the method for monitoring and diagnosing periodic vibrating phenomenon in which observation is made from the constituent equipment of an engineering system, the vibration model of a neural network 1 is constructed by preparing teacher data based on a trajectory reconstructed from observed time sequential data and time sequential data observed at arbitrary time are compared with the temporal development of the output of the vibration model constructed of the neural network 1 to which an initial value is given from the time sequential data.;COPYRIGHT: (C)1999,JPO
