Design for the Contact Force Planner in Upper Limb Rehabilitant Robot Based on Fuzzy Control and Impedance Control

The most fitting force is crucial for stroke patients' upper limb by the rehabilitation robot to train. However, in the existed force planner, the contact force is too mutational to fit the training demand. A kind of force planner was proposed to generate the gradual changed force in this paper. The method combines fuzzy control and impedance control to improve the mutational force. Simulation and experiment results show that the adopted method can be confirmed safer and more comfortable.
