Design Criteria Multi-Loop Flight Control Systems

The problems of design criteria and architecture of multiloop flight control systems are discussed for a realized system to achieve precise flight path guidance, safe and economic control of the aerodynamic flow airspeed, angle of attack and lift coefficient control and passenger comfort. Joint root locus and quality criteria design presented. The structure of the presented multiloop flight control system consists of nonlinear open loop control for flight performance and flight management purpose, superposed quasi linear state vector feed back and six control surfaces aileron, rudder, elevator, trim, throttle, direct liftdrag control.
