FLIGHT CONTROL SYSTEM AND METHOD FOR A CONVERTIBLE FIXED-WING DRONE PROVIDING A STABILIZED CONTINUOUS TRANSITION BETWEEN A VERTICAL STATIONARY FLIGHT AND A HORIZONTAL CRUISE FLIGHT

摘要

A flight control system is configured to control the flight of a convertible fixed-wing drone (12), having two left and right wings, each supporting a propeller in front and a deflection flap at the rear edge. The control system includes an attitude regulator (154) of the drone (12) to respectively control the roll angles ϕm, pitch θ m and yaw Ψm, measured by one or more sensors on setpoint angles ϕd, pitch θ d and lace Ψd. The first attitude regulator (154) comprises a first MFC SISO device (162) for modelless control at one input-one output for regulating and controlling the pitch angle θ m measured on the pitch set angle θ d by determining a first command δn for symmetrical deflection of the left and right flaps, applied with the same sign to said left and right flaps.
