Hydraulic system simulation of CVT with fuzzy logic controllers

The article establishes the hydraulic system model of the continuous variable transmission and designs the fuzzy logic controllers. Two main hydraulic symbols (guide-overflow valve and solenoid valve) are introduced. And analyzes the application of PWM in hydraulic system. To improve controlling accuracy, parameter self-adjustable fuzzy control is used. The simulated models of the two sections of the hydraulic system are established and the simulated results are good. The hydraulic system´s experimental results are given.
