โœฆ Synopsis

We present geometric design techniques for observer design in generalized state-space or singular systems. The unknown-input-conditioned invariant subspaces are defined for singular systems, and are related to the solution of a generalized Lyapunov equation. The approach emphasizes solution procedures based on the Lyapunov equation and a singular system structure algorithm. This paper extends the singular system observer theory both by providing a geometric basis for it and showing the best that may be accomplished if the system is not observable.

Necessary and sufficient conditions for the decoupting of singular systems using P-D (proportional derivative) feedback are determined. Given a system which satisfies these conditions, the class of all feedback matrices which decouple the system is characterized. This class is used to determine the

Qualitatively independent systems, a previously recognized type of combinatorial design, have been recently shown to have industrial applications involving the testing of complex systems. For these applications, even small reductions on the size of a qualitatively independent system can be significa
