Simulation and Fuzzy Control Study on the CVT Metal V Belt Axial Misalignment of Car
Based on the analysis of the belt misalignment of the metal V belt CVT the reason of the belt misalignment has been discussed.In order to control the misalignment.an electro.hydraulic control system has been designed.After deeply analyzing the structure and principle of the electro-hydraulic conffol systern,the mathematical model of the electro.hydraulic control system has been established.Being varieties of the working situation of car and the non-linearity of the electro-hydraulic control systern,A Fuzzy PID algorithm has been designed.Then the simulmion of the belt misalignment has been conducted,and the simulation results show that the electro-hydraulic COntrol system and the fuzzy controller could not only control ratio.which had a higher accuracy of the stable state and a stronger robust of the driving condition,but also eliminated the belt misalignment,improved the dynamic performance of the metal V belt CVT.
