A type of double proportional valves in synchronization control of double non-symmetrical cylinder is introduced. Then the working principle and dynamic response mathematical-model of the proportional valve in controlling non-symmetrical cylinder are discussed. The mathematic expressions of synchronous errors are given. By using of the model and expressions and through dynamic software of simulink, non-linear imitation models of general hydraulic components are built, and the establishment of imitational models and the modification of component parameters in graphical interation are implemented. Then high-precise synchronization actions of the double cylinders are finished.
