Ein Modalmaß für Beobachtbarkeit und perspektivische Beobachtbarkeit linearer zeitinvarianter Systeme

Translated title of the contribution: A modal measure for observability and perspective observability of linear time-invariant systems

Research output: Contribution to journalArticle

Abstract

The modal measure due to Litz is a simple method for quantitatively assessing a system's observability. In some cases, however, it does not correctly reflect the loss of observability caused by eigenvalues with multiplicities greater than one. The present contribution proposes an extension that remedies this problem. It is furthermore shown that this modified measure can easily be extended to assess also a system's perspective observability. The practical applicability of the measure is demonstrated in the course of an illustrative example.
