Developments of High Performance Fluid power Automation

摘要

Closed loop control of hydraulic systems offers an excellent means to control fast movements with big loads and high forces. However hydraulic servo drives have a lot of anomalies, like non linearities, which in some applications make these systems demanding to control. In these cases special control features are required in order to get the most out of the drive. The developments described in this paper are aimed at providing the industry with a standard tool for tackling such applications. Easy and fast realization, together with excellent performance have been guideline for these activities. The end result is a servo control platform which is versatile enough to handle the simplest through to the most complex problems and which is applicable to electric drives as well as hydraulic drives.
