A Singular Perturbation-Like Approach to EDFA Gain Control Based on Observer Techniques

Design of EDFA Gain Controller based on Disturbance Observer Technique

Based on a theoretical erbium-doped fiber amplifier (EDFA) model, we have proposed an application of disturbance observer(DOB) with proportional/integral/differential(PID) controller to EDFA for minimizing gain-transient time of wavelength -division-multiplexing (WDM) multi channels in optical amplifier in channel add/drop networks. We have dramatically reduced the gain-transient time to less t...

A new Approach to the Multi-Objective Control of Linear Singular Perturbation Systems

A High Gain Observer based LMI Approach

This paper deals with the observability analysis and the observer synthesis of a class of nonlinear systems. The observer that we consider has a constant gain and concerns a class of uniformly observable systems. A sufficient condition permitting to design such a constant gain observer is given. The calculation of this gain is based on LMI technics.Copyright c © 2008 IFAC

A Singular Perturbation Approach to Control of Lightweight Flexible Manipulators

The control of lightweight flexible manipulators moving along predefined paths is the focus of this work. The flexible manipulator dynamics is derived on the basis of a Lagrangian-assumed modes method. The full order flexible dynamic system does not allow the determination of a tracking control as for rigid ma~ipulators, since there are not as many control inputs as output variables. Thi~ drawb...
