[Abstract]:In order to meet the requirements of intelligent operation and high quality operation of construction machinery, based on the principle of pump valve compound control and independent control of inlet and outlet, a combined control strategy of lifting speed and position of boom based on mode switching is proposed. According to the target position and running speed, the desired trajectory is designed. The proposed control strategy enables the working process of the boom to run according to the expected trajectory, and enables the boom to locate precisely when the position is close to the target. On the basis of making full use of the energy-saving characteristics of the independent control system of import and export, the compound control of velocity position is realized. The mechanical-electro-hydraulic simulation model is established, the feasibility of the control strategy is analyzed and the parameters are predicted, and the test system is further constructed and the test study is carried out. The results show that the moving arm can run smoothly according to the set trajectory and realize high precision positioning. This study can provide reference for automatic operation and high quality operation of construction machinery.
