H∞次优滤波在角速度匹配传递对准中的应用
The Angular Rate Matching of Transfer Alignment by using H∞Filter
摘要
Abstract
The measurement of angular rate matching is the difference of gyro between Master Inertial Navigation System(MINS)and Slave Inertial Navigation System(SINS).The measurement of angular rate matching is used the Kalman filter to achieve the optimal estimate of Inertial Navigation System.By constructed and analysis of the state equation and measurement equation of angular rate matching,the paper uses the H∞ filter to estimate the installation error and misalignment of attitude when the elastic deformation of the wing is considered as colored noise.The results of simulation shows that the H∞ filter of angular rate matching can effective restrict the disturbance of the elastic deformation of the wing,while it can guarantee the robust performance to improve the precision of angular rate matching and the rapidity of angular rate matching.As a flight of Transfer Alignment,the H∞ filter of angular rate matching is more accorded the engineering practice when the system noise and measurement noise are color noises.关键词
