Design of a nonlinear disturbance observer
IEEE Transactions on Industrial Electronics, 2000This paper presents a new disturbance observer based on the variable structure system theory for minimum-phase (with respect to the relationship between the disturbance and output) dynamical systems with arbitrary relative degrees. The model uncertainties and the nonlinear parts of the system are merged into the disturbance term and are regarded as a ...

On the observer design for descriptor systems
[1991] Proceedings of the 30th IEEE Conference on Decision and Control, 1993Summary: For the descriptor system \(E\dot x= Ax+ Bu\), \(y= Cx+ Du\), an observer of the order \(p=\text{rank }E- p_ 1\) (\(0\leq p_ 1\leq\text{rank }E\)) is developed. It is not assumed that the descriptor systems are necessarily regular. The derivation is straightforward using only an algebraic approach.

Design of observers for descriptor systems
IEEE Transactions on Automatic Control, 1995Summary: In this note straightforward methods to design full- and reduced-order observers for linear time-invariant descriptor systems are presented. The approach for the reduced-order observer design is based on the generalized Sylvester equation. Sufficient conditions for the existence of the observers are given. An illustrative example is included.

The Ring: Observation and Design
2014The previous chapter completed the presentation of the logical structure of control systems by introducing two important generalizations: (1) multi-lever control systems and the concept of control strategy; (2) multi-objective control systems and the concept of control policy.

An easy design for interval observers
International Journal of Control, 2019This paper deals with the problem of interval estimation. The proposed approach is based on the use of successive derivatives in continuous time (or forward measurements in discrete time) in an alg...

New techniques for the design of observers
IEEE Transactions on Automatic Control, 1984New efficient algorithms are presented for designing reduced observers both for the estimate of the state and for that of a given linear functional of observable, linear time-invariant systems (A,B,C). It is shown that for almost all matrices G, such that the pair (F,G) is reachable, the matrix \(\left( \begin{matrix} C\\ V\end{matrix} \right)\) is of ...

Design observations for interagency collaboration
Government Information Quarterly, 2014Abstract We present 14 design observations for public safety networks (PSNs) and describe how they may apply more broadly to a wider range of inter-organizational systems within the public sector. A PSN is an interagency collaboration focused on developing and using information systems in support of information sharing and functional interoperability

On robust observer compensator design
Automatica, 1988This paper presents, for the first time, a unified, explicit and restriction free set of design formulas for Kalman type and Luenberger type state observers and function observers, with arbitrary poles. In addition, a new, explicit and deterministic observer pole selection method for recovering the robustness of a direct state feedback system is also ...
