Several Typical Nonlinear Filtering Algorithms and Performance Analysis
LIU Xiangyang
Abstract：For the nonlinear filtering problem,firstly,the general principles and filtering steps of several typical nonlinear fil?tering methods are introduced,and the advantages and disadvantages of each filter are briefly described. Secondly,a classic non-linear example is used to compare the performance of each filter. The research results show that the EKF has a small amount of calculation,the PF has high precision,and the UKF and CKF have high accuracy and strong real-time performance.
