The first German edition of this book appeared in 1972, and in Polish
translation in 1976. It covered the analysis and synthesis of
sampled-data systems. The second German edition of 1983 ex- tended the
scope to design, in particular design for robustness of control system
properties with respect to uncertainty of plant parameters. This book is
a revised translation of the second Ger- man edition. The revisions
concern primarily a new treatment of the finite effect sequences and the
use of nice numerical proper- ties of Hessenberg forms. The introduction
describes examples of sampled-data systems, in particular digital
controllers, and analyzes the sampler and hold; also some design aspects
are introduced. Chapter 2 reviews the modelling and analysis of
continuous systems. Pole shifting is formulated as an affine mapping,
here some n w material on fixing some eigenvalues or some gains in a
design step is included. Chapter 3 treats the analysis of sampled-data
systems by state- space and z-transform methods. This includes sections
on inter- sampling behavior, time-delay systems, absolute stability and
non- synchronous sampling. Chapter 4 treats controllability and reach-
ability of discrete-time systems, controllability regions for con-
strained inputs and the choice of the sampling interval primarily under
controllability aspects. Chapter 5 deals with observability and
constructability both from the discrete and continuous plant output.
Full and reduced order observers are treated as well as disturbance
observers.
