Sliding mode controller design for a class of forging system

A nonlinear system model for a class of forging and hydralic system is constructed. On the basis of the conversion of its model, a sliding mode controller is designed which considers the upper limit of perturbation. The simulation result shows that a position tracking with high precision is realized, and it has a better disturbance-resistant ability. So it proves that the designed controller can achieve the scheduled demand and has a good effect.
