Abstract :
The electrohydraulic (EH) synchronized motion of two linear ram type hydraulic actuators is considered in this paper. Load and hydraulic component uncertainties are limiting the synchronization performance of open-loop type control approaches. A synchronizing adaptive robust control (ARC) algorithm is proposed to improve synchronization performance. Simulation results verified the effectiveness of the proposed ARC method as compared to the deterministic robust control (DRC) method
