一种简化的拟蒙特卡洛-高斯粒子滤波算法
A Simplified Quasi-Monte Carlo Based Gaussian Particle Filter
摘要
Abstract
A simplified Quasi-Monte Carlo Gaussian particle filtering(QMC-GPF)(SQMC-GPF) algorithm is presented to solve the problems of high complexity and large amount of computation that QMC method is faced with when it is applied to GPF.In this algorithm,a basic set of particles which obey unit quasi-Gaussian distribution are pregenerated with the method of QMC before the successive iterative filering process,and then they are converted to the particles needed during iterative filering by means of linear transformation,without the QMC method called again.This algorithm simplifies the generation of new particles,reduces the amount of computation and filtering time,and improves the real-time performance of the QMC-GPF algorithm.Finally,the PF,GPF,QMC-GPF and SQMC-GPF algorithms are simulated with univariate nonstationary growth model(UNGM) and bearing-only tracking model(BOT).Results show that,SQMC-GPF algorithm has much higher filtering speed than QMC-GPF algorithmon on the premise of the same filtering performance,which proves that the former has important practical application value.关键词
