Abstract A novel trajectory tracking strategy is developed for a double actuated swing in a hydraulic construction robot. Specifically. a nonlinear hydraulic dynamics model of a double actuated swing is established. and a parameter adaptive sliding mode control strategy is designed to enhance the trajectory tracking performance. https://www.bekindtopets.com/hot-save-Fresh-n-Clean-Scented-Shampoo-15-1-Concentrate-Crisp-Linen-Gallon-great-choice/
