Hysteresis from dynamically pinned sliding states
We report a surprising hysteretic behavior in the dynamics of a simple one-dimensional nonlinear model inspired by the tribological problem of two sliding surfaces with a thin solid lubricant layer in between. In particular, we consider the frictional dynamics of a harmonic chain confined between two rigid incommensurate substrates which slide with a fixed relative velocity. This system was pre...
متن کاملHysteresis in Dynamically Pinned Sliding States
We analyse the occurrence of bistability and hysteretical behavior in the underdamped motion of a simple one-dimensional lubricated friction model inspired by the tribological problem of two incommensurate sliding surfaces with a thin sheet interposed. This system was recently found to possess exact velocity plateaus for large parameters intervals, showing a remarkable quantization of the cente...
متن کاملPinned films and capillary hysteresis in microfluidic channels.
Pinned water films in a microfluidic channel act as elastic membranes under tension that increase capillary pressures while preserving the mechanical work dissipated around capillary pressure-saturation, P(c)-S(w), hysteresis cycles. High-resolution two-photon laser micromachining of SU-8 photoresist was used to fabricate wedge-shaped microfluidic channels that included sharp edge features to p...
متن کاملNeural Sliding Mode Control for Hysteresis Systems
In this paper, a neural network based adaptive sliding mode control scheme for hysteretic systems is proposed. In this control scheme, a neural network model is utilized to describe the characteristic of hysteresis. Then, the adaptive neural sliding mode controller based on the proposed neural model is presented for a class of single-input nonlinear systems with unknown hysteresis. For the case...
