摘要:
提出一种在无高精度测试转台的场合下,精确辨识加速度计误差参数的方法。所提方法以静态多位置加速度模方为观测量,以重力加速度模方误差的标准方差为指标,利用人工鱼群算法对加速度计误差进行辨识。对静态24位置进行仿真分析,在此基础上,对实验室自行研制的光纤捷联惯导系统进行加速度计参数辨识,并进行了24 h静态导航试验。仿真和试验均表明,所提方法是一种有效的加速度计参数辨识方法,具有一定的工程实用价值。
Abstract:
An accurate method of identifying accelerometer error parameters in the absence of high precision test turntable is proposed. The method takes static multiposition acceleration norm for observation and stan dard variance of norm error of acceleration gravity for index, identifying error parameters of accelerometer with artificial fish swarm algorithm. Simulation analysis on the static 24 positions is made and the accelerometer parameters identification on fiber optic gyro strapdown inertial navigation system is developed. In addition, a 24 hours static navigation test is taken. Both the simulation and test results show that the identification method for error parameters of accelerometer provided by the article is effective and has a certain practical value.
