改进粒子滤波算法对电动汽车电池SOC的估计
An Improved Particle Filter Algorithm for SOC Estimation of Electric Vehicle Battery
摘要
Abstract
In order to solve the problem of lacking SIR particle filter algorithm diversity,the SIR particle filter algorithm is improved to estimate electric vehicle battery state of charge (SOC),with system state continuous approximate distribution sampling regularization filtering algorithm.By the ampere hour method to build the state space model of the battery and identify the battery model parameter,the simulation experiment is finished combined with the particle filter algorithm and improved particle filter algorithm in MATLAB.Simulation results show that,the SIR particle filter algorithm estimation errors of SOC becomes larger with the time increasing,the improved particle filtering algorithm to estimate the battery state of charge (SOC) has been close to the true value.Compared with the SIR particle filter,the improved particle filtering algorithm is of high accuracy and better adaptability than the SIR particle filter algorithm,providing a new idea for estimating SOC of batteries used in electric vehicles.关键词
