In this paper, single, two-position, two-way proportional valve is used to carry out the positon control
of asymmetrical hydraulic cylinder with two chambers connected. The system structure and the working princle
are introduced. The dynamic model of the asymmetrical hydraulic cylinder system is established with power bond
graphs method, and becomes a fundament for analyzing the system. Sliding mode controller is designed, and
the stability of the control system is analyzed. The simulation results indicate that the sliding mode controller
designed can actualize the position control of asymmetrical hydraulic cylinder system, and controller is superior
to traditional PID controller when the load changes in some range.
