Perturbation estimation in sliding mode motion control
1999 European Control Conference (ECC), 1999A perturbation estimation sliding mode based motion control algorithm was introduced for a class of nonlinear mechatronics systems in the presence of structured and unstructured uncertainties and external disturbances. The effects of these uncertainties are combined into a single quantity called perturbation.

Static sliding-motion phenomena in dynamical systems
IEEE Transactions on Automatic Control, 2003We present a new type of sliding motion which results from a novel choice of the sliding surfaces. We define these sliding surfaces such that they become explicitly dependent on the outputs of the discontinuous block. We prove under this design, a special sliding mode characterises the system dynamics, which we name static sliding mode, because it ...

Auxiliary Sliding Motions of Vibro-Impact Systems
Automation and Remote Control, 2020In motion control systems, modes with more and more frequent switching are known. For systems with impacts (a certain class of impulse systems), an analog of these modes is motions with an infinite number of impact interactions occurring in a finite time. For such motions, a description in terms of smooth differential equations is proposed.

Sliding motion in image registration
2014The approach for image registration presented in Chapter 3 aims at finding a transformation that is optimal with respect to a similarity measure and a smoothness condition that ensures a physiologically plausible motion. One of the major challenges for such registration methods in the context of this work is the occurrence of sliding motion – a ...

Image Registration with Sliding Motion Constraints for 4D CT Motion Correction
2015A common assumption in medical image registration is that the estimation of a globally continuous deformation field is plausible in reality. However, a sliding behavior of adjacent organ boundaries (e.g. lung and ribcage) cannot be described in a plausible way by a continuous deformation field.
