On structures of combined uav flight control systems with elements of fuzzy logics

SUMMARY

The paper deals with flight control system development in a form of successive loop control that involves “crisp” and fuzzy contours. The paper explores peculiarities of sharing the control functions between “crisp” and fuzzy parts of the developed autopilot. The division of the autopilot structure into “crisp” and fuzzy parts is performed by applying the H? -robust stability theory of fuzzy systems and the describing function approach. The design procedure is illustrated by a case study of unmanned aerial vehicle lateral channel control. It was proved that application of the fuzzy control is expedient for outermost contour in the successive loop structure of flight control system
