Novel electro-hydraulic leveling suspension system of electric tractor and control method of novel electro-hydraulic leveling suspension system

The invention provides a novel electro-hydraulic leveling suspension system of an electric tractor and a control method of the novel electro-hydraulic leveling suspension system. The structure that the single-side leveling hydraulic cylinder is matched with the lifting rod is adopted, the rotation angle and the inclination trend of the transverse position of the suspended agricultural implement are controlled by adjusting the telescopic amount of a piston rod of the hydraulic cylinder, and adjustment of the relative position of the agricultural implement and the ground is achieved. And the error and the error rate of the inclination angle are adjusted in real time by adopting a control mode of a fuzzy PID algorithm. The real-time levelness of the machine tool is guaranteed through a center-fixed leveling method, and the relational expression of the expansion amount of a lifting hydraulic cylinder or the angle change value of a mechanical lifting arm corresponding to the ploughing depth ...
