This paper describes a method for power assist control that calculates the joint torques necessary to support an assist suit wearer’s walking. We approximate the body using a multijoint rigid link model. Joint support torques are calculated based on this model using the hip, knee and ankle angles of the wearer. Results of experiments show the effectiveness of proposed control method.
