Multi-Objective Design Assessment and Control Law Synthesis Tuning for Flight Control Development

Abstract

Flight control law design is a multi-variable control problem where various strict requirements from multiple disciplines have to be satisfied. This paper describes multi-objective control synthesis tuning and design assessment, with application to flight control design. The main feature of this methodology is that the various kinds of design objectives can be taken into account in their most natural form and design alternatives can be assessed most visibly with respect to given requirements. Multi-objective synthesis tuning by min-max parameter optimisation allows interactive compromising in the set of what can be best-possibly achieved with a chosen control law structure.
