트랙터의 전자 유압식 히치 제어 시스템에 관한 연구 (III) -컴퓨터 시뮬레이션-
Electronic-Hydraulic Hitch Control System for Agricultural Tractors (III) -Computer Simulation-
초록
The purposes of this study were to perform theoretical analysis of an electronic-hydraulic hitch control system for position and draft control of tractor implements and to investigate the performance of the control system through computer simulation. Computer simulation models which could predict the responses of the system to the step and sinusoidal inputs in position and draft controls were developed using the simulation package "TUTSIM". The effects of control mode, hydraulic flow rate, deadband, and proportional constant on control performance of the system were investigated. The simulated results were compard with the experimental ones to verify the simulation models. The simulation models appeared to be a useful means for the analysis and the design of the electronic-hydraulic hitch control system.
