摘要
对拖拉机线控液压转向系统进行了总体设计,详细分析了其结构组成和工作原理,并通过对比分析得出了系统的最优控制算法。采用模糊控制作为系统的控制算法,实现了前轮转角的闭环控制技术;最后采用Matlab/simulink对整个系统进行仿真,得出了油缸位移的响应曲线,验证了系统设计的准确性。
The author conducted the overall design for the wire - controlled hydraulic steering system of tractor, analyzed its structure and working principle in detail, and obtained the optimal control algorithm of the system through the comparative analysis. The fuzzy control algorithm was used to realize the closed - loop control technique for the steering of the front wheel in the system. In the end, Matlab/simulink was used for the simulation of the entire system. The simulation got the response curve of oil cylinder dis- placement, and verified the accuracy of the design for this system.
