In this study, nonlinear second order systems with unmeasured system states and bounded external disturbances are considered. The observer gain of the sliding mode observer is adjusted by using a support vector machine based plant model. Computer simulations are presented to show the effect of the proposed adjustment mechanism on the performance of the output feedback sliding mode controller. I...

The conventional sliding mode controller needs the exact knowledge of system state measurements. In this study, nonlinear second order systems with unmeasured system states and bounded external disturbances are considered. The sliding mode observer based on nonlinear observation error dynamics is considered and the observer gain is adjusted by using a support vector machine based plant model. F...

The development of a sliding hydrogel with mobile crosslinks and biochemical ligands as a 3D stem cell niche is reported. The molecular mobility of this sliding hydrogel allows stem cells to reorganize the surrounding ligands and change their morphology in 3D. Without changing matrix stiffness, sliding hydrogels support efficient stem cell differentiation toward multiple lineages including adip...

The physics of motion of a sliding object can be used to plan sensorless robot manipulation strategies based on sliding. Prediction of a sliding object's motion is difficult because the object's distribution of support on the surface, and the resulting frictional forces, are in general unknown. We describe a new approach to the analysis of sliding motion, which finds the set of object motions f...

The physics of motion of a sliding object can be used to plan sensorless robot manipulation strategies. Prediction of a sliding object’s motion is difficult because the object’s distribution of support on the surface, and the resulting frictional forces, are in general unknown. This paper describes a new approach to the analysis of sliding motion, which finds the set of object motions for all d...

To e ciently support continuous display for continuous media many approaches based on the striping strategy that is implemented on a multi disk drive have been proposed However the striping strategy can only support simultaneous display of continuous media which are predetermined before they are stored in the multi disk drive For an interactive display application a system must support users to...

The DNA backbone is often considered a track that allows long-range sliding of DNA repair enzymes in their search for rare damage sites in DNA. A proposed exemplar of DNA sliding is human 8-oxoguanine ((o)G) DNA glycosylase 1 (hOGG1), which repairs mutagenic (o)G lesions in DNA. Here we use our high-resolution molecular clock method to show that macroscopic 1D DNA sliding of hOGG1 occurs by mic...

In this paper, sliding mode non-linear control is applied to force reflecting teleoperation. Various forms of the sliding mode control law are derived for force feedback master manipulator with an arbitrary factor for force and position scaling. Experiments were performed on a one axis test system and frequency domain hybrid 2-port matrices are measured and compared between the sliding mode con...
