Abstract

How to eliminate the extra torque is a key problem of electro-hydraulic load system. Aimed at the characteristic of electro-hydraulic load system extra torque, different from conventional compensation methods, a rudder pressure feedforward compensation method is proposed. The mechanics of extra torque is analyzed by building the integrated model of electro-hydraulic load system. Then the rudder pressure feedforward compensation controller is built. Finally the simulation and experiment are operated by different controllers. Simulation and experiment results show that the proposed method can eliminate extra torque efficiently.
