摘要
捷联式电子罗盘正被大量应用,根据其自身观测能力,提出了一种新的姿态及姿态速率估计方法,该优化估计方法采用加权统计线性回归技术,与经典的对非线性系统方程的线性化的方法相比具有更高的精度和稳定性。仿真结果表明,该方法可以明显提高捷联式电子罗盘的姿态测量精度,并能同步完成对姿态速率的估计,直接扩展捷联式电子罗盘的功能。
A recursive optimal attitude and attitude-rate estimation algorithm for strapdown electric compass is presented. Weighted statistical linear regression to avoid linearization of nonlinear system equation is applied in the algorithm. The simulation result show that the proposed method would improve the precision of measurement and extend the function of compass obviously.
