Abstract
Electro-hydraulic servo system has been used in many industrial applications for high power in size, high response and fine repeatability. But, load variation causes a degradation of control characteristic. In this paper, we introduce a scheduling parameter which is a function of hydraulc force against load, and apply it for gain scheduled controller design to maintain steady control performance under comparatively large load variation. Furthermore, we take time-delay into consideration as modeling error so that achieve desirable follow-up performance. Usefulness of this approach is confirmed by experiments.
