基于动力性模糊控制拖拉机遥控换挡设计研究
Research on Remote Shift Design of Tractor Based on Dynamic Fuzzy Control
摘要
Abstract
In order to realize the remote shifting of tractor,this paper designs an electronically controlled hydraulic shifting system based on the dynamic fuzzy control shifting,and builds a simulation model in AMEsim.According to the speed regulation characteristics of the engine,a dynamic gear shift strategy is established with the throttle opening,current vehi-cle speed and gear as input parameters.According to the driver's intention and tractor status,a secondary fuzzy controller is established to correct the dynamic shifting strategy.The working conditions were set,the tractor transmission system model was established in MatLab/Simulink,and the joint simulation of AMEsim-Simulink was used to obtain the displace-ment curve of the piston rod of the hydraulic cylinder,and the feasibility was verified.Compared with the traditional shift-ing and the dynamic fuzzy control shifting,the clutch impact and sliding friction work were used as the control targets for simulation analysis.The results showed that the system control effect designed in this paper is better than that of traditional gear shifting,and meets the dynamic adaptability of tractor.关键词
