Adaptive Flight Control in the Presence of Multiple Actuator Anomalies

This paper evaluates the performance of an adaptive flight control in the presence of multiple actuator anomalies such as failures, control saturation and matched uncertainties. A baseline inner-loop PI controller is designed and augmented with an adaptive controller. It is proven that for an unstable (stable) open-loop plant the proposed controller solves the bounded tracking problem locally (globally). Theoretical derivations are validated using simulations of a nonlinear 6 DOF aircraft model with realistic actuator constraints and failures.
