A flight controller design method with a fixed controller architecture and which satisfies given handling quality requirements is proposed. The new methodology, mainly based upon guardian maps, first translates handling qualities in terms of eigenvalue confinement or linear constraints, then tunes gradually the parameters of the controller until the requirements are satisfied; i.e., essentially until all -or part of- closed-loop poles lie within a specified region of the complex plane. An example that illustrates the longi-tudinal flightcontroller design of a Challenger 604aircraft is presented on 20 different points of the flight envelope. The methodology is successfully applied using two different longitudinal flight controller architectures of interest, namely pitch attitude hold control and C-star mixed output control.
