Abstract
This paper present a control design of the VCCTEF (Variable Continuous CamberTrailing Edge and Flaps) aircraft, which is an elastically shaped aircraft with highly flexiblewings. This aircraft has the capability to actively change the wing twist and bending inflight so as to achieve a local angle of attack distribution that is optimal for the specificflight condition. The aircraft dynamic model is that of a large-scale system with 1463states and 39 control surfaces, which include 32 flaps on the wings that change the wingcamber actively in flight. A decentralized controller that uses the conventional controlsurfaces (ailerons, elevator and rudder) to control only the slow modes, and the wingflaps to control the fast modes, is developed. This decentralized controller also has thecapability to optimize the drag consumption while also adapting to uncertainties in theaircraft model. Simulation results demonstrate the validity of this decentralized optimaladaptive controller architecture.
