Abstract:A novel trajectory tracking strategy is developed for the swing DOF with double actuated cylinder in a hydraulic construct robot. When the work object is grabbed and unload, the inertia parameter of swing varies greatly and the estimation algorithm is commonly insufficient. Aiming at this feature, a novel nonlinear hydraulic dynamics model is established for the double actuated hydraulic cylinder in the system and a robust adaptive control strategy with parameter adaptive estimation is designed to improve the … Show more
