摘　　要：通过分析飞行器运动方程,给出了分段线性化模型簇描述.为了得到一定飞行区域的鲁棒控制器,选取负实极点并采用对角占优势的方法对状态反馈矩阵进行设计.同时,提出了全飞行区域(飞行包线内)的多个子系统划分及鲁棒镇定控制的设计方法.为了抑制飞行器的建模误差,采用了输入补偿方法.与常规鲁棒控制设计方法相比较,该方法可以降低飞行控制器设计的复杂度.飞行控制器设计结果表明,该方法对不确定系统的分析和设计是有效的.Through analyzing the motion equation, the manifold models with segmented linearization are provided. Negative real closed-loop poles are allocated and diagonally dominated criterion is used to determine state feedback matrices. For whole flight region, subsystems are used and multi-feedback matrices are designed. Moreover, an input compensation is given to decrease the influence of modeling errors. Comparing with ordinal robust control methods, the new method can reduce the complex designing of aircraft controller. Designing for an aircraft shows that the new method can give satisfactory results.
