This monograph presents the state of the art in aeroservoelastic (ASE)
modeling and analysis and develops a systematic theoretical and
computational framework for use by researchers and practicing engineers.
It is the first book to focus on the mathematical modeling of structural
dynamics, unsteady aerodynamics, and control systems to evolve a generic
procedure to be applied for ASE synthesis. Existing robust, nonlinear,
and adaptive control methodology is applied and extended to some
interesting ASE problems, such as transonic flutter and buffet,
post-stall buffet and maneuvers, and flapping flexible wing.
The author derives a general aeroservoelastic plant via the
finite-element structural dynamic model, unsteady aerodynamic models for
various regimes in the frequency domain, and the associated state-space
model by rational function approximations. For more advanced models, the
full-potential, Euler, and Navier-Stokes methods for treating transonic
and separated flows are also briefly addressed. Essential ASE controller
design and analysis techniques are introduced to the reader, and an
introduction to robust control-law design methods of LQG/LTR and H2/H∞
synthesis is followed by a brief coverage of nonlinear control
techniques of describing functions and Lyapunov functions. Practical and
realistic aeroservoelastic application examples derived from actual
experiments are included throughout.
Aeroservoelasiticity fills an important gap in the aerospace
engineering literature and will be a valuable guide for graduate
students and advanced researchers in aerospace engineering, as well as
professional engineers, technicians, and test pilots in the aircraft
industry and laboratories.
