Title:Control optimization of digital hydraulic drive for knee exoskeletonAuthor(s):Rituraj Rituraj, Rudolf ScheidlAbstract:A successful knee exoskeleton device must follow the periodic motion of the gait cycle in an energy efficient manner. This work investigates an optimal control strategy that can allow the periodic behavior of such a device with minimum error while also consuming minimum energy. Using a multi-objective optimization technique, a trade-off between the periodicity error and energy consumption is demonstrated. From the pareto front, an optimal control variable set is determined which allows an acceptable periodic behavior of the knee exoskeleton with negligible energy consumption.Booktitle:ENOC 2022 - 10th European Nonlinear Dynamics Conference, July 17-22, Lyon, France.Page Reference:2 page(s)Publishing:7/2022
