【Abstract】 Based on the control scheme for force and position,a control and testing system of metal V-belt CVT is developed in this paper.Taking into account the complex nonlinear characteristics of the CVT shift dynamics and the saturated nonlinear characteristics of the speed ratio control valve,a fuzzy ratio controller based on ratio feedback is designed.The test results show that the developed hydraulic control system is practical and feasible.更多还原
