利用对误差函数加权的最优控制,提出了具有固定增益的鲁棒飞行控制系统的设计方法。用该方法设计的控制系统不仅具有稳定的鲁棒性,而且具有操纵品质的鲁棒性。本文研究了该鲁棒飞行控制系统在全飞行包线内的稳定性,还对某歼击机设计了鲁棒飞行控制系统。设计和仿真表明了该方法的简便性和有效性。 相似文献

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
