基于AMEsim的拖拉机自动耕深控制系统仿真研究

摘要

设计了拖拉机自动耕深控制系统,介绍了其组成与工作原理,提出了新型的液压油路,并选定液压元件参数.根据真实作业情况,建立了基于AMEsim的液压悬挂力位综合控制系统仿真模型.在仿真模型的基础上,设计了系统PID 控制器,通过阶跃与正弦信号输入分析系统的响应性及抗干扰能力,进一步查看系统各主要元件的压力与流量变化情况,验证液压元件设计参数的可行性.%A tractor tilling depth automatic control system was designed,and the composition and working principle was introduced.Put forward a new type of hydraulic circuit and parameters of main hydraulic components were selected.Ac-cording to the actual operation situation,the simulation model of hydraulic hitch force and position synthesis control sys-tem based on AMEsim was established.PID controller of the control system was designed.Responsiveness and Anti-inter-ference ability was analyzed through step and sine signal input,meanwhile,oil pressure and flow rate of main components were checked,and the feasibility of the design parameters was verified.
