Sliding mode functional observers
2008 10th International Conference on Control, Automation, Robotics and Vision, 2008In this paper the concept of sliding mode is introduced in the design of functional observers. Conditions for the existence of the observer are given. How to design the observer parameters are also shown. Under special circumstances the sliding mode functional observer proposed in this paper reduces to the Utkin state observer.

Sliding Mode Control With Sliding Perturbation Observer
Journal of Dynamic Systems, Measurement, and Control, 1997This work introduces a new robust motion control algorithm using partial state feedback for a class of nonlinear systems in the presence of modelling uncertainties and external disturbances. The effects of these uncertainties are combined into a single quantity called perturbation. The major contribution of this work comes as the development and design

Sliding mode observer for fluid flow
2017 IEEE Conference on Control Technology and Applications (CCTA), 2017Many phenomena in science and engineering are described using partial differential equations. However, for the systems modeled by PDEs, having access to the states of the system can be challenging due to technical difficulties such as lacking enough sensors in the system. In this paper the problem of estimating the parameters of fluid flow described by

Sliding-mode observers for uncertain systems
2009 American Control Conference, 2009Sliding-mode observer design is considered for linear systems with unknown inputs when the so-called observer matching condition is not satisfied. To circumvent the restriction imposed by the observer matching condition, the method of utilizing auxiliary outputs generated by high-order sliding-mode exact differentiators in the sliding-mode observer ...

Sliding mode observer for Switched Linear Systems
2011 IEEE International Conference on Automation Science and Engineering, 2011This work is concerned with the design of an observer for Switched Linear Systems (SLS) subject to an unknown switching signal. The convergence of the proposed SLS observer is proved, based on observability results for SLS, for the following two cases.

Sliding mode observers: a survey
International Journal of Systems Science, 2008Sliding mode observers have unique properties, in that the ability to generate a sliding motion on the error between the measured plant output and the output of the observer ensures that a sliding mode observer produces a set of state estimates that are precisely commensurate with the actual output of the plant. It is also the case that analysis of the

Sliding mode observers. Tutorial
Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002Discusses the problem of designing observers for state estimation using sliding modes. The theory and design principles are presented for linear and nonlinear systems. For linear systems the observers are developed using a block-observable form which is similar to a lower triangular matrix form. Compared with known approaches such observers have better

Sliding mode observers for vehicle mode detection
Vehicle System Dynamics, 2005This paper explores the use of sliding mode observers to detect the onset of potentially dangerous vehicle modes such as oversteer, understeer or split-μ braking. Provided these modes can be detected quickly enough, existing stability controllers can be engaged to ensure safe performance of the vehicle.

The focus of much of the research in the area of control systems theory during the seventies and eighties addressed the issue of robustness - i.e., designing controllers with the ability to maintain stability and performance in the presence of discrepancies between the plant and model.
