Abstract: A system to control uasymmetrical cylinder position by a proportional valve was studied. The mathematical model of the electro hydraulic proportional-position control system with pipeline was built. Two models of the control system, with and without pipeline, were investigated by computer simulation. The effect of pipeline has an effect on the stability of electro-hydraulic proportional-position control system. The length and diameter of the pipeline and the flow-pressure coefficient can obviously inflect the stability of the system.
