Abstract

Coal-gas outbursts produce acoustic emission signals(AE). Giving the problem of extracting more pure and effective AE signals, this paper proposed an intelligent optimized particle filter(PF) of neighborhood dynamic adjustment(D) for fruit fly algorithm(FOA). It used each fruit fly individual characterizing signal particle of PF to optimize the resampling process of particle filtering, and adjusting the number of neighboring particles dynamically improved the optimization ability and convergence rate of fruit fly algorithm. Taking the root-mean-square error and signal-to-noise ratio as the evaluation index, from signal acquisition system, it respectively de-noised the AE signals of coal-gas outburst by standard particle filter, fruit fly optimized particle filter and improved particle filter. The experiment results show that the signal-to-noise ratio of the optimized particle filter algorithm is improved by about 15.3 dB, and the root-mean-square error is the lowest. Compared with other two methods, the improved particle filter has the best de-noising effect.
