In the present study, we investigate the stick-slip phenomenon and friction behaviour of
industrial ball bearing linear guides to get some precise and comprehensive data on this …

The random responses of Duffing systems with dynamic friction are investigated, and a
uniform procedure is established to derive the explicit expressions of stationary probability …

High demands of precision on machine tools are hardly cope by using existing classic
control algorithms. This paper focuses on the design, analysis and validation of a super …

An inverted pendulum is a classic case of robust controller design. A successfully validated
and precise system model would greatly enhance the performance of the controller making …

In this paper, an online identification and compensation method of nonlinear friction based
on radial basis function (RBF) neural network model is proposed for the influence of …

The high demand in tracking performance is crucial in machine tools application. Therefore,
the purpose of this paper is to design a Nonlinear PID (NPID) controller for improvement of …

This study investigates the frictional sliding dynamics occurring at the interface between two
bodies in contact by using the Maxwell-slip model at the microscopic scale. The elastic body …

Accurate and precise positioning control is critical in designing a positioning servo
pneumatic system. The internal friction force of the pneumatic is one of the disturbances that …
