Electro-Hydraulic Servo Control System Based on a Novel Generic Model Control Method

A novel electro-hydraulic servo control algorithm was introduced. The primary idea of this algorithm was to combine the notion of model prediction with the generic model control (GMC). The performance of the GMC algorithm was improved by receding optimization and feedback correction. By the predictive model of output errors of an electro-hydraulic servo control system based on the improved weighted least square support vector machines (WLS-SVM) to forecast and compensate the future sequence errors, the control precision and robustness were improved. The improved GMC based on the improved WLS-SVM was applied to an electro-hydraulic servo control system for hot strip rolling control systems. The simulation results showed the feasibility and effectiveness of the present algorithm.
