This paper addresses the effect of actuator anomalies on flight control design, with particular emphasis on loss of effectiveness and actuator saturation. An adaptive controller with an integral action and a resetting strategy is proposed to address the actuator anomalies.We show that the stability of the closed-loop system can be guaranteed and that the controller allows a graceful degradation of...
Presented here is an L1 adaptive control architecture for a generic transport aircraft. At its core, this architecture features a three-axis, non-linear, dynamic inversion controller. Command inputs for this baseline controller are provided by pilot roll-rate, pitch-rate, and sideslip commands. This paper will first thoroughly present the baseline controller followed by a description of the L1 adaptive...
By using an interactive architecture of independently designed guidance and active fault tolerant control systems, this work proposes the development of a novel Guidance and Active Fault Tolerant Control Scheme for a fixed wing Unmanned Aerial Vehicle. As to the guidance segment, an approach, of the Feedback Linearization type, has been exploited for developing, directly on the dynamic model of the...
