Synthesis and analysis of the controller of the parameters of the lateral movement of an unmanned aircraft during the takeoff phase

Сonsiders the design of a robust regulator for a light unmanned airplane lateral motion parameters at the takeoff stage. The regulator is synthesised using the 2-Riccati approach of H∞ theory at three points of the trajectory. The properties of a system containing regulators with three sets of coefficients are compared with a system using one stationary regulator. Transient characteristics of flight path azimuth control, as well as roll and sideslip motion, are considered. The behavior of the aircraft under the action of a crosswind and inaccurately specified aerodynamic characteristics is analysed. The performance of a dynamic stationary robust regulator obtained at one trajectory point is shown throughout the entire takeoff stage of the airplane.
