Nonlinear Attitude Filter on SO(3): Fast Adaptation and Robustness

Ajay Singh, Trenton S. Sieb, James H. Howe, Hashim A. Hashim

摘要:

与高斯姿态滤波器和其他姿态确定方法相比,非线性姿态滤波器被认为具有更简单的结构和更好的跟踪性能。非线性姿态滤波器设计的一个关键因素是误差准则的选择。非线性姿态滤波器的传统设计在快速自适应和鲁棒性之间进行权衡。在这项工作中,提出了一种新的功能的方法,基于模糊规则的在线连续调整的非线性姿态滤波器自适应增益。同时考虑姿态误差和姿态误差变化率,采用人工蜂群优化算法对输入输出隶属度函数进行优化调整。该方法在大误差时具有高的自适应增益,在小误差时具有小的自适应增益。因此,所提出的方法允许快速收敛性能与高的鲁棒性措施。仿真结果表明,该方法具有鲁棒性和高收敛能力,对大的初始化误差和不确定的测量。

英文摘要:

Nonlinear attitude filters have been recognized to have simpler structure and better tracking performance when compared with Gaussian attitude filters and other methods of attitude determination. A key element of nonlinear attitude filter design is the selection of error criteria. The conventional design of nonlinear attitude filters has a trade-off between fast adaptation and robustness. In this work, a new functional approach based on fuzzy rules for on-line continuous tuning of the nonlinear attitude filter adaptation gain is proposed. The input and output membership functions are optimally tuned using artificial bee colony optimization algorithm taking into account both attitude error and rate of change of attitude error. The proposed approach results of high adaptation gain at large error and small adaptation gain at small error. Thereby, the proposed approach allows fast convergence properties with high measures of robustness. The simulation results demonstrate that the proposed approach offers robust and high convergence capabilities against large error in initialization and uncertain measurements.
