| Abstract: | 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 displacement,and verified the accuracy of the design for this system. |
