In this paper, we develop a novel adaptive control architecture that ensures that the input
and output of an uncertain linear system track the input and output of a desired linear system …

This paper addresses a new trajectory tracking controller for quad-rotor aircrafts in the
presence of time-varying aerodynamic effect and bounded external disturbance using the …

In this paper, we present a novel adaptive control architecture that ensures that the input and

In this paper we present an extension of the L1 adaptive control architecture to nonlinear
systems in the presence of significant uncertain cross-coupling. To evaluate the L1 adaptive …

Verification and Validation (V&V) of gain-scheduled flight control systems relies on analysis
of gain and phase margins across the flight envelope. Because similar tools are not …

This paper proposes an adaptive fuzzy logic control scheme for a class of strict-feedback
nonlinear systems with unknown backlash-like hysteresis. The proposed controller exploits …

This paper presents results of a flight test of the L-1 adaptive control architecture designed to
directly compensate for significant uncertain cross-coupling in nonlinear systems. The flight …

This paper presents the L 1 adaptive controller for a class of multi-input multi-output
nonlinear systems in the presence of unmatched uncertainties. The L 1 controller ensures …

A number of challenges in the development and application of flying qualities criteria for
modern aircraft are addressed in this dissertation. The history of flying qualities is traced …

This note presents novel adaptive output feedback control methodology for systems of
unknown dimension in the presence of unmodeled dynamics and time-varying uncertainties …
