內容簡介：
Recent technological developments have forced control engineer to deal with
extremely complex systems that include uncertain, and possibly unknown,
nonlinearities, operating in highly uncertain environments. The above, together
with continuously demanding performance requirements, place control
engineering as one of the most challenging technological fields. In this
perspective, many "conventional" control schemes fail to provide solid design
procedures, since they mainly require known mathematical models of
the system and/or make assumptions that are often violated in real world
applications. This is the reason why a lot of research activity has been concentrated
on "intelligent" techniques recently.
One of the most significant tools that serve in this direction, is the so called
artificial neural networks (ANN). Inspired by biological neuronal systems,
ANNs have presented superb learning, adaptation, classification and functionapproximationproperties, making their use in on line system identification
and closed-loop control promising.
Early enrolment of ANNs in control exhibit a vast number of papers
proposing different topologies and solving various application problems. Unfortunately,
only computer simulations were provided at that time, indicating
good performance. Before hitting real-world applications, certain properties
like stability, convergence and robustness of the ANN-based control architectures,
must be obtained although such theoretical investigations though
started to appear no earlier than 1992.
The primary purpose of this book is to present a set of techniques, which
would allow the design of
? controllers able to guarantee stability, convergence and robustness for dynamical
systems with unknown nonlinearities
? real time schedulers for manufacturing systems.
To compensate for the significant amount of uncertainty in system structure,
a recently developed neural network model, named Recurrent High Order
Neural Network (RHONN), is employed. This is the major novelty of this
book, when compared with others in the field. The relation between neural
and adaptive control is also clearly revealed.
It is assumed that the reader is familiar with a standard undergraduate
background in control theory, as well as with stability and robustness concepts. The book is the outcome of the recent research efforts of its authors.
Although it is intended to be a research monograph, the book is also useful
for an industrial audience, where the interest is mainly on implementation
rather than analyzing the stability and robustness of the control algorithms.
Tables are used to summarize the control schemes presented herein.
Organization of the book. The book is divided into six chapters. Chapter
1 is used to introduce neural networks as a method for controlling unknown
nonlinear dynamical plants. A brief history is also provided. Chapter
2 presents a review of the recurrent high-order neural network model and analyzes
its approximation capabilities based on which all subsequent control
and scheduling algorithms are developed. An indirect adaptive control scheme
is proposed in Chapter 3. Its robustness owing to unmodeled dynamics is analyzed
using singular perturbation theory. Chapter 4 deals with the design
of direct adaptive controllers, whose robustness is analyzed for various cases
including unmodeled dynamics and additive and multiplicative external disturbances.
The problem of manufacturing systems scheduling is formulated
in Chapter 5. A real time scheduler is developed to guarantee the fulfillment
of production demand, avoiding the buffer overflow phenomenon. Finally, its
implementation on an existing manufacturing system and comparison with
various conventional scheduling policies is discussed in Chapter 6.
The book can be used in various ways. The reader who is interested in
studying RHONN's approximation properties and its usage in on-line system
identification, may read only Chapter 2. Those interested in neuroadaptive
control architectures should cover Chapters 2, 3 and 4, while for those wishing
to elaborate on industrial scheduling issues, Chapters 2, 5 and 6 are required.
A higher level course intended for graduate students that are interested in
a deeper understanding of the application of RHONNs in adaptive control
systems, could cover all chapters with emphasis on the design and stability
proofs. A course for an industrial audience, should cover all chapters with
emphasis on the RHONN based adaptive control algorithms, rather than
stability and robustness.
