| Abstract: | According to the random errors of the MEMS(Micro-Electro-Mechanical-Systems)gyro,particle filtering algorithm is introduced.By means of Singer model of Moving Target,the system state equations are presented.The application of the particle filtering algorithm in the output data of MEMS gyro is discussed and the algorithm is deduced in detail.In this paper,Kalman filtering and particle filtering are used in filtering to the initial alignment output data of MEMS IMU respectively.By using two kinds of filtering method,the random errors are reduced,and the particle filtering is better. |
