An Improved Particle Filter Algorithm Based on UKF and Linear Optimization Method
Abstract：Due to the degenerac existing in the particle filter,a new combined particle filter algorithm is presented in this paper.Which based on the unscented Kalman filter（UKF） altorithm and linear optimization method.In the proposed algorithm,unscented Kalman filter algorithm is used to generate the importance proposal distribution,and the linear optimazation method is applied to enhance the diversity of samples with using all particles contribute to the state estimate.The Monte Carlo simulation results show that the improved particle filter can solve the degenerac in particle filter and has a good accuracy in state estimating.
