HYDRAULIC SERVO SYSTEM USING A FEEDBACK LINEARIZATION CONTROLLER AND DISTURBANCE OBSERVER

Abstract

In this study, the control performance of a hydraulic servo system with a feedback linearization compensator is investigated. The focus of this study is set on the quantitative investigation of the effects(sensitivities) of disturbances and system parameters' variation on control performances of the hydraulic control system. Finally, verifies the efficacy of a disturbance observer to overcome the control performances deterioration due to system parameters' variations, disturbances in the control system.
