This paper presents a new electro-hydraulic servo control method. This method introduces model predictive into generic model control (GMC). By receding optimization and makes feed-back correction, GMC performance is improved. Using improved weighted least square Support Vector Machines (WLS-SVM) to forecast and compensate the future sequence errors, the system’s precision and robust ness were increased. It elementary solved the systems delay, nonlinearity and time variability. The GMC based on improved WLS-SVM are applied to electro-hydraulic servo control system in hot mill. The result of a numerical simulation experiment shows the feasibility and effectiveness of this algorithm
