| 摘 要： | 采用摄动参数多项式加范数有界摄动形式描述大包线飞控系统,既考虑了飞控系统的时变特征,又考虑了拟合误差带来的不确定性.基于二次稳定的概念和方法,研究了大包线飞控系统的鲁棒稳定性分析和鲁棒控制综合问题.运用线性矩阵不等式(LMI)的处理方法,给出了系统二次稳定性判据,以及状态反馈控制律的设计方法.同时,基于凸优化,得到了估计系统保持鲁棒稳定所允许的参数最大摄动范围的方法,建立了系统运行参数与系统性能之间的联系.通过对飞控系统的实例仿真,验证了该方法的可行性.

| Abstract: | Large envelope flight control systems are described in the form of polynomial related to perturbation parameter and norm-bounded perturbation.Both the time-varying characteristic and the uncertainty from fitting error are considered in this paper.The problem on robust stability analysis and stabilization for large envelope flight systems is concerned based on the concept of quadratic stability.Based on linear matrix inequality(LMI) approach,a quadratic stability criterion is addressed.Also this approach is ... |
