Abstract：To solve the problem that the traditional electro-hydraulic hitch could not adapt the lateral angel for tillage on slope, a feedback control system of adaptive electro-hydraulic hitch was designed. The method of predicting the hitch lateral inclination angle was proposed by Kalman prediction algorithm. The dynamic model of lateral inclination angle adaptive electro-hydraulic hitch was set up. The control system model with the above dynamic model of hitch was established in Simulink. The actual measured transverse slope was used as model input signal to verify the performance of control system. The results show that the fluctuation of lateral tillage error can be controlled within±10 mm.
