Adaptive Patient Support for Rehabilitation Robots

چکیده
Zusammenfassung Rehabilitationsroboter unterstützen die Rehabilitation von Patientenmit Bewegungsstörungen aufgrund von Schädigungen des Nervensystems. Neu entwickelte, patientenkooperative Regelungsansätze sollen es diesen Robotern ermöglichen, individuell an die Patienten angepasste, effektivere Trainingseinheiten durchzuführen, als dies bislang möglich war. Dieser Beitrag beschreibt zwei Ansätze zur automatischen Anpassung der Roboterunterstützung: Die iterativ lernende Vorsteuerung ermöglicht die Unterstützung von Bewegungen mit definiertem zeitlichem Ablauf. Das iterativ lernende, konservative Kraftfeld ermöglicht die Unterstützung von Bewegungen mit freiem zeitlichem Ablauf. Das Verhalten beider Verfahren wird an einer Beispielanwendung mit dem Gang-Rehabilitationsroboter Lokomat demonstriert. Summary Rehabilitation robots support rehabilitation of patients with neurological movement disorders. Newly developed patient-cooperative control approaches aim at enabling the robots to perform more effective trainings, which are tailored to individual patients. This paper presents two approaches to automatically adapt robotic support: The iterative learning feedforward control is able to support movements with defined timing. The iterative learning conservative force field can also support movements with free timing. Both approaches are demonstrated in an example application with the gait rehabilitation robot Lokomat.

A New Intelligent Approach to Patient-cooperative Control of Rehabilitation Robots
This paper presents a new intelligent method to control rehabilitation robots by mainly considering reactions of patient instead of doing a repetitive preprogrammed movement. It generates a general reference trajectory based on different reactions of patient during therapy. Three main reactions has been identified and included in reference trajectory: small variations, force shocks in a single ...
متن کاملFunction Approximation Approach for Robust Adaptive Control of Flexible joint Robots
This paper is concerned with the problem of designing a robust adaptive controller for flexible joint robots (FJR). Under the assumption of weak joint elasticity, FJR is firstly modeled and converted into singular perturbation form. The control law consists of a FAT-based adaptive control strategy and a simple correction term. The first term of the controller is used to stability of the slow dy...

Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...
