Aerospace Instrument-Making Annotation << Back Synthesis of integrated control system in longitudal motion of unmanned aerial vehicle during landing Lebedev G.N. Kurmakov D.V. In the article the task of automatic control of unmanned aerial vehicle on glide path descending is solving, by respecting the coordination between thrust and altitude control. Linearization of three-dimensional motion unmanned aerial vehicle equa-tions on landing causes the separate regulators synthesis in the vertical and actual motion channels, that eliminating the possibility of interaction. In the synthesis of integrated landing control with non-linear flight model is proposed to use dynamic programming Bellman function as a third order polynome, which led to the formation of two-dimensional quasi-linear regulator. During the definition of the regulators transfer coefficients it was possible to obtain an analytic solution in quadratures¸ which is easy to realize on the unmanned aerial vehicle platform, if flight conditions are changed. Further elaboration and improvement of the integrated control system should continue by using computer modelling of spatial movement of an unmanned aerial vehicle considering influence of the wind and difference between air and ground speed.
