    Abstract
  • Based on the characteristics and the demands of synchronization, a single nero forecast controller was presented,which was designed to eliminate synchronization error of upset force in flash butt welding. A press feedback loop was designed to solve the problem that it is uneasy to assemble force sensor in flash butt welding. In view of the characteristics of hydraulic system, a nonlinear hydraulic system and a coupling model of mechanical system were designed in AMESim by control library and mechanical library,and the controller was designed in Simulink. In order to verify the performance of the new designed controller, the parameters of hydraulic system between branches were set different. An interface between controller and hydraulic system was designed in Simulink and AMESim, by which the eletro-hydraulic co-simulation was achieved. The result shows that the forecast controller exhibits excellent performance on eliminating synchronism of upsetting force in flash butt welding.
