Abstract

Today there are ever-increasing demands for more efficient hydraulic drive technology in terms of reducing energy consumption, increasing reliability plus robustness, and for minimising the maintenance interventions on the drive. In addition, the requirements and directives on the reduction of the noise, and development tendencies in the direction of environmentally user-friendly drives, are leading to an ever-increasing usage of the electro-hydraulic drive technology. There are two main concepts for converting electrical into hydraulic energy: constant speed motor coupled with variable displacement pump and variable speed motor coupled with constant pump. This article presents completed PhD tasks including modelling and simulation of both of the two concepts along with a new concept of variable speed motor coupled with constant pump. All the concepts are compared in dynamics and efficiency based on the simulation results. The expected results of the PhD are a newly-synthesized SIMO controller for ’bi-variable’ control, that will be able to control hydraulic systems in order to operate within the areas of maximum efficiency, highest dynamics or a compromise between these two. A further contribution to the hydraulic system developers’ community will be an experimentally proven mathematical model for the simulations of different hydraulic drive concepts. Such a model may be used for optimising the energy-efficiencies of existing and new hydraulic machinery, as well as efficiency prediction when building new hydraulic systems. Moreover it may also be used for determining the most suitable drive concept for a hydraulic system with a predefined operating cycle.
