This paper studies force couple leveling system of heavy hydraulic press. A multi-input and multi-output nonlinear model is established on the basis of analyzing hydraulic structure and block kinematics. A cascade control structure is designed for the leveling system. In the outer loop, each corner follows the average displacement other two corners adjacent to it using PI method, and the desired pressure...
A fourth-order system model for a class of hydraulic forging system is constructed. According to the characteristics of nonlinearity and uncertainty, a control method for a high order system which is based on backstepping theory is proposed,and a self-adaption algorithm for relevant parameter is deduced from the Lyapunov Theorem. It solves the problem which a forging system cannot realize a demand...
