The simulation of the three-way valve control cylinder system is studied for the nonlinearity and time-varying in control problem. Mathematical model and dynamic equations are established based on the physical model and frame model of three-way valve control cylinder. Fuzzy logic control strategy is adopted for the time-varying of system, and nonlinear simulation model is established based on two-dimension fuzzy logic controller. The simulation results suggest that the performance of proposed fuzzy logic controller is satisfied.
