MOTION SYNCHRONIZATION FOR ELECTRO-HYDRAULIC SERVO-DRIVES

Abstract

Keywords: This article presents a control algorithm that solves the problem of motion synchronization for a system of three electro-hydraulic drives. The designed control system takes into account not only position errors for individual drive axes, but also synchronization errors with neighboring axes. The synchronization function for the control system, which takes into account the positioning errors of individual drive axes was specified. Experimental results on a 3-cylinder system were presented to verify the effectiveness of the proposed approach.
