Eigenvalue Assignment

The output feedback eigenvalue assignment problem for discrete-time systems is considered. The problem is formulated first as an unconstrained minimization problem, where a three-term nonlinear conjugate gradient method is proposed to find a local solution. In addition, a cut to the objective function is included, yielding an inequality constrained minimization problem, where a logarithmic barrier method is proposed for finding the local solution. The conjugate gradient method is further extended to tackle the eigenvalue assignment problem for the two cases of decentralized control systems and control systems with time delay. The performance of the methods is illustrated through various test examples.

Survival Of The Fittest

Recent developments in the control systems of aeroplanes have been such as to underline the need for new terms, and the need to remove any ambiguity relating to terms already in existence. The question has also been raised by the British Standards Institute in relation to the revision of the Glossary of Aeronautical Terms. The present paper examines the problem in the light of possible future developments, lists proposed terms with their definitions, and gives an outline of the underlying arguments. It is written in the spirit that in the field of systems of units, notation, and nomenclature “survival of the fittest” will always apply. The details of the nomenclature are not considered all-important, but we have tried to select the right concepts, to classify sensibly, and to produce accurate and general definitions. We expect many useful and amusing comments on nomenclature, but the other aspects are the fundamental ones, and we hope there will be some constructive criticism.
