Due to the inherent nonlinear nature of magnetorheological (MR) dampers, one of the
challenging aspects for developing and utilizing these devices to achieve high performance …

High-precision motion control is highly desirable in process and industrial automation,
including the domains of machine tools, ultra-precision spindles, micro-manufacturing …

Structured and unstructured uncertainties are the main obstacles in the development of
advanced controllers for high-accuracy tracking control of hydraulic servo systems. For the …

This paper concerns high-accuracy tracking control for hydraulic actuators with nonlinear
friction compensation. Typically, LuGre model-based friction compensation has been widely …

In this article we first review properties of the LuGre model, including zero-slip displacement,
invariance, and passivity. An extension to include velocity-dependent microdamping is also …

Covering fractional order theory, simulation and experiments, this book explains how
fractional order modelling and fractional order controller design compares favourably with …

One of the most important properties of neural nets (NNs) for control purposes is the
universal approximation property. Unfortunately,, this property is generally proven for …

Modeling and identification of mechanical systems constitute an essential stage in practical
control design and applications. Controllers commanding systems that operate at varying …

Generally, the valve controlled electro-hydraulic systems are able to achieve high motion
tracking precision, but suffer from large amount of throttling losses. As an alternative …

In this paper, a novel sliding-mode-observer-based adaptive controller is developed for the
servo actuators with friction. The LuGre dynamic friction model is adopted for adaptive …
