This paper presents a nonlinear cascade controller based on an extended disturbance
observer to track desired position trajectory for electro-hydraulic single-rod actuators in the …

Most recent studies on adaptive hydraulic tracking control focus on the trajectory tracking
performance while the parameter convergence property is often unsatisfying. This article …

The paper describes a simulation study that provides a comprehensive comparison between
full-active and semi-active suspensions for improving the vertical ride quality of railway …

A passivity framework for hydraulic actuators is developed by considering the
compressibility energy function for a fluid with a pressure-dependent bulk modulus. It is …

Addressing the simulating issue of the helicopter-manipulating booster aerodynamic load
with high-frequency dynamic load superimposed on a large static load, this paper studies …

Implementation of immersion and invariance (I&I) theorem becomes increasingly difficult as
the degree of freedom increases. This inherent difficulty is mainly driven by the need to solve …

Continuing recent works of the authors, the paper shows the developing and the application
of a neuro-fuzzy control law to the positioning loop of a hydrostatic type servoactuator …

Forwading-based immersion and invariance approaches have been applied to control the
high-order nonlinear systems, whereas it is an off-line algorithm and needs to directly …

The design of nonlinear tracking controller for antagonistic tendon-driven joint has garnered
considerable attention, whereas many existing control methodologies are impractical in the …

There are only a few methods for controlling high-order nonlinear systems, except for
standard backstepping technique. Due to the fact that I&I theory proposed by Astolfi and …
