Research on Fuzzy Control of the Hydraulic System for Continuously Variable Transmission

Abstract:

Velocity ratio control is one of the key techniques of vehicle metal V-belt type CVT. In this paper, the working principle and hydraulic control system principle of the metal V-belt type CVT were introduced; the mathematic model and fuzzy self-adaptation PID control model of the velocity ratio electrohydraulic proportional control system were established and simulated. It was found that, fuzzy self-adaptation PID control system makes actual velocity ratio change as it was expected with good steady-state characteristics and dynamic response characteristics.
