โœฆ Synopsis

Abs~ract~A new nonminimal representation of reducedorder observers of order n-r in the time and in the frequency domain is introduced. This reduced-order observer is based on a full-order plant model where the order reduction to n -r results from an infinite gain feedback of r outputs. This new representation is crucial for establishing the links between time and frequency domain design methods incorporating reduced-order observers. The main result are the doubly coprime fractional representations of a transfer matrix related to an observer of order n -r.

An observer-based multirate control system design problem is considered. First, the reduced-order multirate observer design of current type is studied on the basis of the mode-decoupling transformation. It is then shown that the state estimates can be achieved by two low-order multirate observers wh

This paper considers the problem of designing an observer to reconstruct a set of linear functionals in the states of a given linear finite-dimensional system. The goal of the present method is the design of least dimension observers having unrestricted spectrum.
