This book presents a general nonlinear control design methodology for
nonlinear uncertain dynamical systems. Specifically, a hierarchical
nonlinear switching control framework is developed that provides a
rigorous alternative to gain scheduling control for general nonlinear
uncertain systems. The proposed switching control design framework
accounts for actuator saturation constraints as well as system modeling
uncertainty. The efficacy of the control design approach is extensively
demonstrated on aeroengine propulsion systems. In particular, dynamic
models for rotating stall and surge in axial and centrifugal flow
compression systems that lend themselves to the application of nonlinear
control design are developed and the hierarchical switching control
framework is then applied to control the aerodynamic instabilities of
rotating stall and surge.
For the researcher who is entering the field of hierarchical switching
robust control this book provides a plethora of new research directions.
Alternatively, for researchers already active in the field of
hierarchical control and hybrid systems, this book can be used as a
reference to a significant body of recent work. Furthermore, control
practitioners involved with nonlinear control design can immensely
benefit from the novel nonlinear stabilization techniques presented in
the book.
