Fault Reconstruction Based on Sliding Mode Observers

2009 WRI World Congress on Computer Science and Information Engineering, 2009
For the momentum wheel control system of satellite, a method to design sliding mode observers for reconstructing actuator fault is presented. It uses the equivalent output injection concept to explicitly reconstruct fault signals, and uses concept to design the sliding motion so that the effect of the uncertainty on the reconstruction of the faults ...

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 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.

Analysis of precision and design of sliding mode observers

2009 IEEE Control Applications, (CCA) & Intelligent Control, (ISIC), 2009
Nominal precision of state observation and bandwidth of sliding mode (SM) observers are analyzed through the frequency-domain method. The previously developed approach to analysis of SM observers as relay feedback-feedforward systems is used and further extended to analysis of effects of design parameter change on observer performance. An example of SM

Sliding mode state observation for non-linear systems

International Journal of Control, 2004
In this paper a class of non-linear systems with uncertainty and a Lipschitz part is considered. The non-linear part satisfies the Lipschitz condition, whilst the uncertain part is a bounded function. A sliding mode observer is designed to yield feedforward compensation input to stabilize the error estimation system with and without a Lipschitz non ...

Adaptive sliding mode control with sliding mode observer for a microelectromechanical vibratory gyroscope

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2008
This paper presents a novel adaptive sliding mode control with a sliding mode observer for a microelectromechanical system (MEMS) gyroscope. The proposed adaptive sliding mode controller with a sliding mode observer can estimate the unmeasured velocities, angular velocity, and damping and stiffness coefficients of the gyroscope in the presence of ...

Sliding Mode Control of Robot Manipulators Based on Sliding Mode Perturbation Observation

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2006
This paper presents a sliding mode controller based on a sliding mode perturbation observer (SMPO) for the tracking control of robot manipulators. The SMPO is designed to estimate unmeasurable states and system perturbations that involve system non-linearities, disturbances, and unmodelled dynamics.

Sliding mode observer based sliding mode controller for interacting nonlinear system

Second International Conference on Current Trends In Engineering and Technology - ICCTET 2014, 2014
This paper presents a comparison study of performances and characteristics of two types of state observer based state feedback control schemes, including Sliding Mode Observer (SMO) based Sliding Mode Controller (SMC) scheme and Luenberger observer (LO) based Sliding Mode Control scheme. The effectiveness of the schemes are simulated and implemented on

A sliding mode observer for the induction motor

Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002
An observer is presented to estimate the magnetic flux components and speed of an induction motor based on stator voltage and current measurements alone. The observer is based on the principle of variable structure systems which immediately offers a number of advantages such as ensured stability, parameter insensitivity, noise rejection, etc.

Sliding Mode Observers for Fault Detection

2011
This chapter considers sliding modes applied to the problem of observer design. The historical development is outlined leading to the description of a specific class of sliding mode observer which will be used throughout the book. It will be shown how the unique properties associated with the so-called equivalent injection signal necessary to maintain ...
