Abstract
Adaptive control is a promising technology for future high-performance, safety-critical flight systems. By virtue of their ability to adjust control parameters as a function of online measurements, adaptive flight control systems offer improved performance and increased robustness. This paper addresses the adaptive control of extremely agile aircrafts in the presence of damages and failures. The FSD ExtremeStar, a modified version of the polystyrene model airplane Multiplex TwinStar II, is used as a platform for this purpose by offering a highly redundant set of control surfaces. The underlying nonlinear model, including the effect of all control inputs, is derived from first principles. A dynamic-inversion PI-error controller is proposed as the baseline controller for a model reference adaptive tracking control. The resulting performance is evaluated for aggressive maneuvers in the presence of elevator failures using the complete nonlinear model.
