A Particle Filter Algorithm Based on SSUKF
As an important nonlinear filter theory,the particle filter(PF) is a heated issue in domestie and foreign reseaches.The optlon of importance denslty and resampHng are the key steps of particle fiIter algorithm.The appHcation of UKF algorithm based on SSUT to create the importance probability density function(PDF).with the particle swarm optimization(PSO),can form a new algorithm of particle filter(PSO-SSUPF).PSO can make the patlcles move to high likelihood area before the weights updating.Consequently, sample lmpoverishment can be restralned to some extent.With the SSUT cutting down the number of slgma points.the efficlency of the algorithm can be considerably improved in the eondition of ensuring the precision being similar with standard UPF,and its performance is confirmed With the simulation.
