Multivariable Fuzzy Control for Prosthetic Hands

Multi-freedom prosthetic hand is multivariable system which has many inputs and outputs. The design of fuzzy logic controller is very complex because so many fuzzy control systems have to be designed based on conventional idea. Thus, a multivariable fuzzy control is proposed. An effective strategy is that all variables share a common membership function and a rule base. It reduces complexity of membership function and rule base. Finally, the proposed multivariable Fuzzy logic controller is used to control a multi-freedom prosthetic hand. The control performance shows that the multivariable is effective.
