摘要：

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. © 1990.
