In response to the problem of insufficient control accuracy in the traditional high-power tractor electro-hydraulic lifting system,a control scheme using multiple feedback parameters for comprehensive adjustment was proposed.By dividing the weights of different feedback control methods,the advantages of each feedback control could be integrated to achieve multi-performance balance.Considering the issue of fixed and immutable weight factors in conventional control,an adaptive change control scheme was proposed based on feedback signals to adjust the weight factors incrementally by utilizing the deviation between the three feedback signals and the set values,so that the weight factors could better meet the changes in performance parameters.Adaptive control rules for the three weight factors and corresponding input and output parameters of the controller were designed respectively.Selecting plowing depth,traction force,and slip rate as evaluation indicators for control performance,a comparative analysis was conducted on non-feedback control,force position comprehensive control and the proposed adaptive control.The results show that the proposed control method has a higher uniformity in plowing depth,the values of traction and slip rate are small,and the variation ranges are significantly smaller than the other two control methods.While improving plowing uniformity,it also improves fuel economy and reduces the impact effect of the suspension system.
