This paper presents a methodical design of the electro-hydraulic control system for a large scale hydraulically driven six-legged robot, which can walk on rough terrain. Considering the widely varying load during the locomotion cycles, the electro-hydraulic control system should be capable of effectively handling widely varying load and possess high control bandwidth. To address these issues, a two-stage...
This paper describes the composition and theory of a new kind of direct drive volume control electro-hydraulic servo system, in order to better express the nonlinear of systems and the input-output relationship of various variables, Power Bond Graph was used to establish bond graph model of the components and overall system, 20-sim software was used to simulation analysis that focus on the impact...
