Flight Dynamics and System Identification for Modern Feedback Control
Author: Jared A Grauer
Publisher: Elsevier
ISBN: 085709467X
Category : Technology & Engineering
Languages : en
Pages : 161
Book Description
Unmanned air vehicles are becoming increasingly popular alternatives for private applications which include, but are not limited to, fire fighting, search and rescue, atmospheric data collection, and crop surveys, to name a few. Among these vehicles are avian-inspired, flapping-wing designs, which are safe to operate near humans and are required to carry payloads while achieving manoeuverability and agility in low speed flight. Conventional methods and tools fall short of achieving the desired performance metrics and requirements of such craft. Flight dynamics and system identification for modern feedback control provides an in-depth study of the difficulties associated with achieving controlled performance in flapping-wing, avian-inspired flight, and a new model paradigm is derived using analytical and experimental methods, with which a controls designer may then apply familiar tools. This title consists of eight chapters and covers flapping-wing aircraft and flight dynamics, before looking at nonlinear, multibody modelling as well as flight testing and instrumentation. Later chapters examine system identification from flight test data, feedback control and linearization. - Presents experimental flight data for validation and verification of modelled dynamics, thus illustrating the deficiencies and difficulties associated with modelling flapping-wing flight - Derives a new flight dynamics model needed to model avian-inspired vehicles, based on nonlinear multibody dynamics - Extracts aerodynamic models of flapping flight from experimental flight data and system identification techniques

Introduction to Flight Dynamics
Author: Giorgio Guglieri
Publisher: Celid
ISBN: 8867892061
Category : Technology & Engineering
Languages : en
Pages : 238
Book Description
This book is intended to serve a diverse audience of students and engineers who are interested in understanding and utilizing the concepts of flight dynamics. The volume provides to the reader the basic principles based on a classical analytical approach. The concepts of controllability and maneuverability are detailed starting from the definition of stability and control of the equilibrium states. Equations for the estimation of hinge moments and stick force in steady and maneuvering flight are provided. The equations of motion are then extended to unsteady flight and a detailed analytical model is derived for dynamic stability analysis, including an interpretation of stability and control derivatives. The modal response of the vehicle in the longitudinal and lateral-directional plane is also reconstructed. The problems inherent in the evaluation of the flying qualities of a fixedwing aircraft and the elements of parameter identification are also introduced. Finally, open and closed loop response to controls is discussed both in time and frequency domain.
