Observer design for interconnected systems with model reduction and unknown inputs

Reduced-order observer design for descriptor systems with unknown inputs

A new method for the design of reduced-order observers for descriptor systems with unknown inputs is presented. The approach is based on the generalized constrained Sylvester equation. Sufficient conditions for the existence of the observer are given.

Full- and reduced-order observer design for rectangular descriptor systems with unknown inputs

In this paper, methods are proposed to design Luenberger type fulland reduced-order observers for rectangular descriptor systems with unknown inputs. These methods are based on the effect of preand post-multiplicative operation of a linear transformation, derived here by means of simple matrix theory. Sufficient conditions for the existence of observers are given and proved. Numerical examples ...

Decentralised observer-based control scheme for interconnected dynamical systems with unknown inputs - Control Theory and Applications, IEE Proceedings-

A completely decentralised observer-based control scheme for interconnected dynamical systems is proposed. The scheme requires no information transfer among the subsystems, local observers or local controllers and applies equally to systems with known and/or unknown disturbances. It is shown that each local observer asymptotically converges to the true state of its corresponding subsystem an4 o...
