Research on Robust Control for Synchronous Control System of the Giant Forging Hydraulic Press Based on the Disturbance Decoupling Observer

摘要

Robust control for synchronous control system of the giant forging hydraulic press based on disturbance decoupling observer is studied against external disturbance, uncertainties of the parameters and uncertainties of the model. Simulation results show: the control strategy in the paper solves the problems of the traditional synchronous control system satisfactorily, which includes low control accuracy, slow dynamic response, bad real-time property, weak antijamming capability Etc., and better improves the dynamic quality of equipment and product quality.
