The main goal of flight clearance is to use the structured singular value (μ) analysis of the flight control system when some pa-rameters in the system vary in a certain range. As the μ-analysis can only be done on a linear fractional transformation (LFT) model, the first step of flight clearance is to generate the LFT model of the flight control system. In this paper, based on the introduction of basic theory of LFT and μ-analysis, an X-fighter is chosen as an example to utilize the proposed methods. In order to realize the flight clear-ance process automatically, a novel software package based on MATLAB programming language is developed. The results of simulation experiments validate the feasibility and effectiveness of the novel methods proposed in this paper. 相似文献

微型飞行器(MAV)体积小、重量轻,设计参数与飞行状态参数的微小变化对其飞行性能影响很大,MAV飞行控制器的设计必须考虑这些不确定性因素。本文对此进行了分析,讨论了对具有参数不确定性的MAV系统进行线性化处理的方法与步骤,针对某无尾MAV的一组优化设计开展了相关研究。 相似文献
