Extended State Observer-Based Sliding Mode Control Design of Two-DOF Lower Limb Exoskeleton
Due to some model uncertainties and unknown friction disturbances that exist in the 2-DOF lower limb exoskeleton, a linear extended state observer (LESO) is proposed to estimate the unmeasurable angular velocity of two joints and the lumped uncertainties caused by friction disturbance and hydraulic...
