Abstract:

Transfer function of matched asymmetric valve cotrolled asymmetric cylinder system was supplied,correcting system load due to asymmetrical characteristics of valve controlled asymmetric roll bending
cylinder system.Control strategy of force control system was studied,such as nonlinearity compensation and dynamic pressure feedback,using matched asymmetric valve to control an asymmetric cylinder.Feasibility employing simultaneous dual-valve to replace matched asymmetric valve in the asymmetric cylinder control system was discussed.Simulation and experimental results verified control strategy concerning dual-valve controlled asymmetric cylinder system.Foundation was established for the analysis and synthesis of asymmetric valve cotrolled asymmetric cylinder system.

Key words: dual-valve control, asymmetric cylinder, nonlinearity compensation, dynamic pressure feedback
