Research on Synchronous Control for Dual-Cylinder System with Unbalanced Loading

Article Preview

Abstract:

To aimed at the synchronous control for dual-cylinder with unbalanced and uncertainty loading, this paper proposes a hybrid control method that consists of feed-forward control and fuzzy feedback control. In the first, a feed-forward controller of each cylinder based on trajectory restrains is developed to limit the motion and synchronous error to a certain extent, and also smooth the piston motion. Then, two fuzzy controllers are specified to improve the tracking performance of cylinder and compensate the synchronous error. The simulation experimental results show that the proposed hybrid control strategy can control the maximum synchronous error of the total system to be within ±10mm under the consideration of large load imbalance, and has the system motion of a good smoothness.
