英文摘要: The application studys the human-exoskeleton coordinate problem of exoskleton system proceeding from enhancing the kinematic response of the human limbs in order to realize the effective power and fast follow of power assisted exoskeleton for wearer.The adaptive coordination control based on emulated inertia compensation is proposed. The power assisted exoskelton of knee joint with tendon sheath will be designed based on the study of human motion biomechanical. The coupled human exoskeleton system with flexible drive will be studied for giving the methodology of the control operation.The emulated inertia compensation controller will be designed and the control method about parametric adaptive control will be studied in order to satisfy the matching and compensating of inertia gain parametric.The stability conditions of control method of human exoskeleton system will be analyzed bsed on stability criterion. The experiments about effect of power assisted and tracking performance of knee exoskeleton will be applied. The results will be give some base for the optimize of exoskeleton. The research results will provide a reliable and stability coordinate control method for human-exoskeleton system.
