Comprehensive treatment of approximation methods for filters and
controllers. It is fully up to date, and it is authored by two leading
researchers who have personally contributed to the development of some
of the methods. Balanced truncation, Hankel norm reduction,
multiplicative reduction, weighted methods and coprime factorization
methods are all discussed. The book is amply illustrated with examples,
and will equip practising control engineers and graduates for
intelligent use of commercial software modules for model and controller
reduction.
