Optimal Control for Tractor Automatic Transmission Shift Process

Abstract:

This paper studies the structure and principle of tractor automatic mechanical transmission shift actuator with the type (electronically controlled hydraulic). Tractor AMT shift actuator mechanics model and mathematical model are set up. Dynamic analysis of shift process is finished. The method of solving contradiction between shift time and shift impact in shift process is presented. Through analysis of shift process, optimal hydraulic control law could be found out by applying optimal control theory. The most short time shift with low impact even no impact is realized.
