Robust controllers with guaranteed implementability through multiobjective optimisation-based design

Abstract

This contribution discusses a novel approach to design of robust controllers explicitly taking into account bandwidth restrictions of onboard computer implemantation. This is achieved by online modal controller reduction during the synthesis-tuning phase in a multiobjective-optimization design environment. This is different to common approaches where implementability issues of high-order controllers are deferred to a separate post-design step. The approach is applied to lateral flight control in the HIRM (High Incidence Research Model) Design Challenge problem defined by GARTEUR.
