飞机侧向运动非线性观测器的研究

本文介绍了几种用来估计飞机侧向运动状态参数——侧滑角β的非线性观测器。地面仿真和试验结果表明,这些观测器结构简单、估计性能好、程序软件简洁易行、计算省时、估计过程迅速,而且具有一定的适应性和抗干扰能力,便于在工程实践中应用。文中详细地给出了各种典型的简化局部非线性观测器的估计方程、原理结构图和部分典型作用下的试验结果。

A RESEARCH OF NON-LINEAR OBSERVERS FOR LATERAL MOTION OF AIRCRAFTS

The paper introduces several non-linear observers which are used to estimate the lateral motion state parameters of an aircraft. The results of ground simulation and experiment are given which show that theseobservers have several advantages. They are simple and easy to implement with good performance and the algorithms possess certain adaptive and anti-disturbance abilities. Simplified estimation equations of nonlinear observers, principle block diagram and the results of experiment are also given in this paper.
