An analog circuit diagnosis algorithm based on dual-loop Volterra filter

摘要

Fault diagnosis algorithm is an important part of power circuit. In order to improve the reliability of power circuit, this paper proposed a novel fault diagnosis algorithm with the dual-loop of Volterra filter. The algorithm utilized the dual-loop of Volterra filter to optimal the parameters of power circuit and remove the noise, then, predict the fault in power circuit by the revised parameters. The simulation show that our proposed algorithm have better convergence speed, training time and the accuracy than the neural network fault diagnosis algorithm and the particle swarm fault diagnosis algorithm.
