Neural identification based on sliding mode observer

2007 IEEE 22nd International Symposium on Intelligent Control, 2007
In this paper, a new on-line neural identification method is presented. The identified nonlinear systems are partial-state measurement. Their inner states, parameters and structures are unknown. The design is based on the combination of a sliding mode observer and a neuro identifier.

Sliding mode observers for fault detection and isolation

Automatica, 2000
This paper considers the application of a particular sliding mode observer to the problem of fault detection and isolation. The novelty lies in the application of the equivalent output injection concept to explicitly reconstruct fault signals. Previous work in the area of fault detection using sliding mode observers has used disruption of the sliding ...

Sliding mode observers for a class of nonlinear systems

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
The stability of a nonlinear observer for systems with uncertainties usually requires some sufficient conditions. In this paper we consider a class of systems with two uncertain parts: one which satisfies the Lipschitz condition, whilst the other does not satisfy the Lipschitz condition but is a bounded uncertainty.

Sliding Mode Control for a Hydrostatic Transmission in Combination with a Sliding Mode Observer

2016
Hydrostatic transmissions are continuously variable hydraulic power converters, which provide lots of advantages and represent a characteristic drive train component in, e.g. all types of working machines, city vehicles and renewable energy plants. In high-performance motion control systems, however, hydrostatic transmissions are less frequently used ...

Sliding Mode Functional Observers for Nonlinear Systems

2008 IEEE Region 10 and the Third international Conference on Industrial and Information Systems, 2008
This paper addresses the problem of estimating a linear function of the states of a nonlinear system using sliding mode functional observer approach. Sliding mode functional observers proposed in this paper are of low-order. New conditions for the existence of sliding mode functional observers are derived.

Conventional Sliding Mode Observers

2014
The purpose of an observer is to estimate the unmeasurable states of a system based only on the measured outputs and inputs. It is essentially a mathematical replica of the system, driven by the input of the system together with a signal representing the difference between the measured system and observer outputs.

On a sliding mode control and observer of induction motor

SMC'03 Conference Proceedings. 2003 IEEE International Conference on Systems, Man and Cybernetics. Conference Theme - System Security and Assurance (Cat. No.03CH37483), 2004
The aim of this paper is to develop a general class of manifolds on which sliding mode flux observation and control of induction motors. For flux-speed tracking, we consider the case where the sliding surface is formed by the derivative of the output tracking error and a function of this error.

Decentralised Sliding Mode Observer-Based FDI

IFAC Proceedings Volumes, 2006
Robust decentralised fault detection and isolation (FDI) is considered in this paper. Firstly, a sliding mode observer is proposed. Then, a decentralised fault estimation strategy is proposed using the equivalent output error injection, and a decentralised reconstruction scheme follows by exploiting the structure of the uncertainty.

An LMI approach for designing sliding mode observers

International Journal of Control, 2001
Presents a method to design sliding mode observers for a class of uncertain systems using linear matrix inequalities. The objective is to exploit the degrees of freedom available in the design which have hitherto been ignored because of the lack of a tractable solution framework.

On the design of Walcott-Zak sliding mode observer

Proceedings of the 2005, American Control Conference, 2005., 2005
This paper explores the design of Walcott-Zak sliding mode observer (WZSMO) for a class of system satisfying some positive real conditions. A new sufficient and necessary existence condition only involving the original system parameters is proposed to simplify the design of WZSMO. The full freedom degree of the design of nonlinear injection of WZSMO is
