In order to enhance the anti-jamming ability of electro-hydraulic position servo control system at the same time improve the control precision of the system, a compound control strategy that combines velocity compensation with Active Disturbance Rejection Controller (ADRC) is proposed, and the working principle of the compound control strategy is given.(More)
In order to improve the work precision, the finite element models of crossbeam of heavy NC gantry moving boring & milling machine were established, and static/dynamic characteristics were analyzed. The crossbeam itself stiffness and the tip displacement converted by beam deformation under the largest cutting force and gravity load were calculated.(More)
In order to avoid unnecessary costs of the design process, we need to design a leg and debug it in advance. It always allows us to determine that whether the design is reasonable. In this dissertation, aiming at the single leg supporting problem of hydraulic quadruped robot in the process of debugging, we design a robot bound planes with guide rails. The(More)
