UAV Aeroservoelastic Control Using Redundant Microactuators.
Abstract
This program is aimed at an improved understanding of nonlinear aeroservoelastic characteristics for uninhabited air vehicles and the evaluation of innovative approaches to UAV control. The work focuses on redundant micro-actuators, and includes the development of methods for aeroservoelastic analysis and design applicable to a wide/range of control strategies. The concepts are of use in the control of vehicles such as high altitude, endurance (HAE) UAV' 5 involving significant aeroelastic coupling with the vehicle dynamics, or uninhabited combat air vehicles (UCAV's ) which require robust control in the presence of observability constraints and aerodynamic nonlinearities. The investigation includes revelation of a new trailing edge effector concept and control law design algorithms required for its synthesis. The multi disciplinary approach involves researchers from several fields, and includes studies of the fluid mechanics of such devices, an innovative approach to manufacturing, and novel control design methods that are well suited to this concept. Present work involves computational and experimental validation tests leading to more comprehensive development and testing in future work.
