The technique of feedback linearization is used to design controllers for displacement,
velocity and differential pressure control of a rotational hydraulic drive. The controllers …

This article proposes a new variable forgetting factor (VFF) bias-compensated recursive
least-squares (BCRLS) algorithm for the recursive identification of complex time-varying …

The characteristics of a hydraulic directional control method for the displacement controlled
system are studied. The directional control is realized by the pilot-operated check valve. The …

PID control and multiloop control schemes are widely used in machine-tool computer
numerical control servo systems. However, fast and efficient tuning methods for solving …

The dynamics of hydraulic systems involves slow and fast modes. These modes are
associated with the mechanical components and those involving fluid flow, respectively. As …

In this paper, we make an initial effort to define the scope and goals of “Cognitive Control
(CoCo)”, which intends to be a research initiative for bringing about a novel generation of …

Hydraulic servo valve controlled differential cylinders are non-linear, strongly coupled
multivariable electromechanical tools applicable for driving eg manipulators. Traditional PID …

Vivemos um tempo em que os recursos naturais começam a ser percebidos como limitados.
A medida que o desenvolvimento científico e tecnológico eleva a expectativa de vida do ser …

In this paper electromagnetic servo valve controlled differential hydraulic cylinders are
considered as paradigms of non-linear systems that have locally nonlinearizable …

Electrohydraulic servosystems have large extent of model uncertainties and generally
difficult to control. The current paper studies the application of the direct adaptive minimal …
