Abstract

This paper presents a nonlinear control approach to the position tracking for a hydraulic actuation system, which consists mostly of a servovalve and an asymmetric single-rode cylinder. The proposed control approach is derived using a sliding mode control strategy. The tracking performance and the robustness against considerable parametric uncertainties (uncertain fluid compressibility, load variations, changes in friction constants, etc.) of the presented control method are demonstrated by both simulations and experiments under various operating conditions
