摘要
介绍了拖拉机电-液悬挂耕深调节系统的结构及工作原理,阐述了建立系统数学模型的方法,同时对其采用PID控制策略,并利用Matlab仿真工具进行了仿真分析,仿真结果表明,PID控制电-液悬挂系统具有稳定性好、控制精度高、响应速度快的优点。
Based on the structure, transmission function and model of tractor electric- hydraulic hitch system, it uses the PID control strategy to electric- hydraulic hitch system and simulates the system with MATLAB. The simulation result shows that the PID control is stable, the model has high precision and rapid response ability.
