Design and Robustness Analysis of Fighter Aircraft Flight Control Laws

In this paper, a complete methodology is detailed for the design and analysis of robust gain-scheduled fighter aircraft flight control laws. The proposed approach consists of three steps. A set of locally robust controllers is first generated using LMI optimization. The global controller is then obtained by a standard linear interpolation and transformed into LFT format. Finally, a validation step is achieved using both LTI and LTVan alysis techniques, for which specific methods and tools have been developed.
