Integrated Flight/Propulsion System H_∞ Controller Design

应用混合灵敏度H∞控制理论研究了综合飞行/推进系统多变量鲁棒控制器设计问题,分析并提出了合理构造和调整加权阵设计综合控制律的方法,针对混合灵敏度H∞控制设计的关键———构造加权阵问题,从加权阵的约束条件和控制系统设计的性能指标两方面入手,通过构造和调整两个加权阵频域特性,以达到对控制系统进行频域整形的目的,仿真结果证明了方法的有效性。

This paper mainly studies multivariable robust controller design methodology for an Integrated flight/propulsion control system based on the hybrid sensitivity H∞ theory. A method about how to build up and adjust an optimal weighted matrix to achieve an integrated control law is presented. Specifically, the major concerns question-selecting weighting functionm matrix （WFM） in hybrid sensitivity H∞ control system design, it launches out on the restriction conditions of WFM and the performance indexes of design, and it is embodied by constructing and ameliorating frequency characteristic of WFM in order to the aim to adjust the frequency characteristic of a control system at last.
