The increasing aging and disabled population has necessitated for a more effective and efficient assistance and rehabilitation. Powered Exoskeletons are wearable robots that can be attached to the disabled limb with the goal of adding power to and rectifying the limb functionality. This research proposes an EMG-based upper limb exoskeleton that is built on a fuzzy controller with incorporation of...
In this paper, a novel neuromusculoskeletal system model for an inverse muscle activity estimation method is proposed. The neuromusculoskeletal system is represented as a state-space equation by standard models in physiology and the proposed neural input model. Conditions for the system observability are investigated and shown that they are physiologically satisfied. Hence, a state observer is utilized...
In this paper, an online estimation method of multijoint human arm viscoelasticity for the case of unknown variance is considered. For the unknown variance process of a human multijoint arm, an estimation method of the human multijoint arm viscoelasticity is proposed. The proposed method includes two estimators, the first estimator is to calculate the variance, and the human multijoint arm viscoelasticity...
