Eigenstructure control involves modification of both the eigenvalues and
eigenvectors of a system using feedback. Based on this key concept,
algorithms are derived for the design of control systems using
controller structures such as state feedback, output feedback,
observer-based dynamic feedback, implicit and explicit modelfollowing,
etc. The simple-to-use algorithms are well suited to evolve practical
engineering solutions.
The design of control laws for modern fly-by-wire high performance
aircraft/rotorcraft offers some unique design challenges. The control
laws have to provide a satisfactory interface between the pilot and the
vehicle that results in good handling qualities (HQ) in precision
control tasks. This book, through detailed aircraft and rotorcraft
design examples, illustrates how to develop practical, robust flight
control laws to meet these HQ requirements.
This book demonstrates that eigenstructure control theory can be easily
adapted and infused into the aircraft industry's stringent design
practices; therefore practicing flight control engineers will find it
useful to explore the use of the new design concepts discussed. The
book, being interdisciplinary in nature, encompassing control theory and
flight dynamics, should be of interest to both control and aeronautical
engineers. In particular, control researchers will find it interesting
to explore an extension of the theory to new multivariable control
problem formulations. Finally, the book should be of interest to
graduate/doctoral students keen on learning a multivariable control
technique that is useful in the design of practical control systems.
