A particle filtering(PF) algorithm based on pigeon-inspired optimization(PIO) is proposed
aiming at problem of sample impoverishment caused by resampling of PF algorithm.When pigeons fly
they usually fly from a far position to high fitness areas constantly.This optimum process is introduced into PF to drive particles moving towards high likelihood areas ceaselessly. And adaptive crossover operation is added to the process of PIO to guarantee the diversity of samples. The nonlinear model simulations experiments show that the precision of the proposed algorithm is improved by 45 % compared with the standard PF algorithm
the stability is improved by72 %
and the number of particles required for the state estimation is reduced at the same time.
