Abstract

The excellent dynamic capabilities of hydrostatic drives with a conventional linear control design are bought at the expense of a poor energetic efficiency. This paper presents a novel approach towards the control of motion of a heavy mass driven by a hydraulic cylinder with a fast valve. The dynamics of the drive are described by a singularly perturbed system of ordinary differential equations. A singular perturbation analysis of this mathematical model results in the suggested control method. Special attention is paid to the compensation of the dry friction at the hydraulic cylinder.
