This book aims to develop systematic design methodologies to model-based
nonlinear control of aeroengines, focusing on (1) modelling of
aeroengine systems--both component-level and identification-based models
will be extensively studied and compared; and (2) advanced nonlinear
control designs--set-point control, transient control and
limit-protection control approaches will all be investigated. The
model-based design has been one of the pivotal technologies to advanced
control and health management of propulsion systems. It can fulfil
advanced designs such as fault-tolerant control, engine modes control
and direct thrust control. As a consequence, model-based design has
become an important research area in the field of aeroengines due to its
theoretical interests and engineering significance. One of the central
issues in model-based controls is the tackling of nonlinearities. There
are publications concerning with either nonlinear modelling or nonlinear
controls; yet, they are scattered throughout the literature. It is time
to provide a comprehensive summary of model-based nonlinear controls.
Consequently, a series of important results are obtained and a
systematic design methodology is developed which provides consistently
enhanced performance over a large flight/operational envelope, and it is
thus expected to provide useful guidance to practical engineering in
aeroengine industry and research.
