In this paper, a new user-friendly platform for robust observer design is presented. The aim of this software is to render the process of observer design as simple as possible for process practitioners and researchers involved in control or supervision tasks. The platform is dedicated to laboratory scale processes in which key variables are not directly measured and therefore need to be estimat...

In this paper, an observer–based controller is designed for the problem of congestion control . In TCP/IP networks, the packets-dropping probability function is considered as a control input. Therefore, the work described here is to design robust observer controller, which is aimed at robust stabilization of network system with uncertainties, input delay and a saturated input. The controller is...

Abstract The aim of this work is to develop a robust control strategy able drive the attitude spacecraft reference value, despite presence unknown but bounded uncertainties in system parameters and external disturbances. Thanks use an extended observer design, proposed law against all that affect high-frequency gain matrix, which shown capture broad spectrum modelling issues, some are often neg...

Robust autopilot design for bank-to-turn (BTT) missiles under disturbances and uncertainties is investigated in this paper using the disturbance observer concept. It is well known that the BTT missile dynamics undergo a substantial changes during its flight. In this disturbance observer based control setting, the influences caused by parameter variations are merged into disturbance terms and re...

This paper addresses the design of a robust set-based interval observer for nonlinear discrete-time system affected by uncertainty (state disturbance and measurement noise) using Takagi-Sugeno (TS) fuzzy model including an unmeasurable premise variable. The effect variable uncertainties is considered as unknown but bounded nature, i.e., in set-membership framework. A zonotopic representation se...

A robust nonlinear observer, utilizing the sliding mode concept, is developed for the dynamic positioning of ships. The observer provides the estimates of linear velocities of the ship and bias from the slowly varying environmental loads. It also filters out wave frequency motion to avoid wear of actuators and excessive fuel consumption. Especially, the observer structure with a saturation func...
