The report is devoted to the design of the robust flight control systems for small UAV,
which have to satisfy contradictory requirements of performans and robustnes from
one hand and low cost and simplicity from other hand. In this report two approaches
of flight control law design pursuing aforementioned goal are proposed: the first is based
on the application of the separation theorem for control law synthesis with further
robustization and simplification of obtained solution, the second is based on the fuzzy
control law learning using robust prototype.
