Abstract :
In this paper, an adaptive fuzzy sliding-mode controller (AFSMC) is proposed to control SMA actuator. An approach of self-tuning fuzzy sliding-mode control which combines fuzzy control with the sliding-mode control (SMC), is presented for the tracking control of a class of nonlinear systems with the parameter uncertainties. Based on Lyapunov theory, the asymptotic stability of the overall systems is proved. The controller is applied to compensate the hysteresis phenomenon of SMA. The control results show that the controller is applied successfully to SMA.
