SYSTEM AND METHOD FOR CONTROLLING THE FLIGHT OF A FIXED-WING CONVERTIBLE DRONE FOR PROVIDING A STABILISED SEAMLESS 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 fixed-wing convertible drone (12) having two left and right wings, each supporting a forward propeller and a trailing flap at the rear edge. The control system comprises an attitude regulator (154) of the drone (12) for respectively controlling the roll angles, φ_m,pitch angles θ_m and yaw angles Ψ_m, measured by one or more sensors over reference roll angles φ_d, reference pitch angles θ_d and reference yaw angles Ψ_d. The first attitude controller (154) comprises a first modelless MFC SISO control device (162) at an input-output for regulating and controlling the pitch angle θ_m measured over the reference pitch angle θ_d by determining a first command δ_n for symmetrical deflection of the left and right flaps, applied with the same sign to said left and right flaps.
