This book presents a solution to a problem in adaptive control design that had been open for 40 years: robustification to disturbances without compromising asymptotic performance. This original methodology builds on foundational ideas, such as the use of a deadzone in the update law and nonlinear damping in the controller, and advances the tools for and the theory behind designing robust adaptive controllers, thus guaranteeing robustness properties stronger than previously achieved. The authors present all stability notions, old and new, that are useful in adaptive control, provide numerous examples, and contrast their analysis to landmark approaches to robustification of adaptive controllers in prior literature.

This book develops the Deadzone-Adapted Disturbance Suppression (DADS) control, a novel adaptive control method, and constructs a novel robust identifier that can work in parallel with every direct adaptive controller (not only DADS); it presents a wing rock instability application of DADS and provides ideas for the extension of DADS to cases not studied in the book.

Robust Adaptive Control: Deadzone-Adapted Disturbance Suppression will be of interest to mathematicians working on feedback control and stability theory and to control engineers. Physicists tackling control problems and biologists with an interest in controlling population dynamics will also find it of interest.
