| 英文摘要 |
| Particle filter (PF) has good estimation performance for nonlinear and non-Gaussian systems, but the lack
of particle diversity has always been the vital problem affecting the estimation accuracy of PF after the introduction of
resampling technology. Therefore, an intelligent PF method based on hybrid adaptive resampling is proposed. Firstly, a
function of computing the covariance matrix adaptively for Gaussian variation is designed in this method on the basis of
hybrid adaptive Metropolis-Hastings (M-H) resampling. Secondly, an acceptance and rejection criterion function using the
mode of survival of the fittest is developed. Finally, the effective particle set is updated in real time to improve the quality
of the particle set and the accuracy of the PF. Two one-dimensional nonlinear models and one high-dimensional nonlinear
model are used to verify the effectiveness of the proposed method. Experimental results show that the proposed method can
effectively improve the quality of the particle after resampling and improve the estimation accuracy of the PF compared
with the existing resampling methods. |
