This paper addresses the output feedback stabilization of an ODE–PDE cascade. The PDE takes form a 1-D reaction–diffusion equation. ODE enters into via Dirichlet/Neumann/Robin boundary condition. It is assumed that both and PDE, selected as Dirichlet trace, are available for control. proposed control strategy finite-dimensional observer-based controller.

Abstract In this paper, we study the stabilization problem of a disk beam structure with disturbance. Specifically, consists clamped at one end to center rotating rigid disk, while other is attached tip mass subject non-uniform bounded We start investigation by designing controller via Active disturbance rejection control (ADRC) approach. The high gain extended state observer (ESO) first design...

This paper addresses two points: first, induction motors are shown to be flat, which implies they can be easily controlled by full-state feedback (for instance with a linearizing (dynamic) feedback); second, an exponential observer, relying on easily measurable variables (stator current and rotor velocity) is proposed.

In the context of parameter estimation through state observers, we revisit the transformation of the induction motor model into a state-affine structure with respect to the unknown variables, then we compare in simulation the performances obtained through available adaptive and exponential forgetting factor observer designs.

A method for sensor fault estimation in multiple-input multiple-output linear time varying systems is proposed in this paper. It is based on a new adaptive observer for joint estimation of states and sensor faults in a state-space formulation of the monitored system. The exponential convergence of the algorithm is proved under some persistent excitation condition. Copyright c ©2005 IFAC

This Letter presents a novel reduced-order nonlinear observer that synchronizes with a given Lorenz chaotic system. We prove the global exponential stability of the resulting error system and illustrate the result with a simulation.  2004 Elsevier B.V. All rights reserved. PACS: 05.45.Xt

This note is concerned with the observer design problem for a class of linear delay systems of the neutral-type. The problem addressed is that of designing a full-order observer that guarantees the exponential stability of the error dynamic system. An effective algebraic matrix equation approach is developed to solve this problem. In particular, both observer analysis and design problems are in...
