Reduced-Order H^ Compensator Design for an Aircraft Control Problem

A recently introduced method for designing //<» compensators based on minimal-order observers is considered for an aircraft control problem. The purpose of this paper is to bridge the gap between theory and application by presenting a practical utilization of a new design approach. Manual flight control systems for the lateral axis of a fighter aircraft are developed using both full-order and reduced-order compensators, and the results are compared. It is demonstrated that this method can be used to directly design reduced-order compensators that result in a system satisfying a closed-loop //« bound.
