Abstract
This paper presents a new cerebellar model articulation controller (CMAC), a sliding-mode-based diagonal recurrent fuzzy CMAC (SDRFCMAC) to robot-assisted rehabilitation for stroke patients. To design the intelligent controller, the CMAC is integrated with some control methods, in which sliding mode technology is used to reduce the dimension of the control system, and fuzzy logic and diagonal recurrent structure is used to solve dynamic problems. The control architecture is represented in terms of stepping optimization system architecture comprising two learning stages to provide robotic assistance for an upper arm rehabilitation task and improve the safety of the human-robot system. Liapunov stability theorem and Barbalat’s lemma are adopted to guarantee the asymptotical stability of the system. The effectiveness of the control scheme is demonstrated through a simulated case study.
