Abstract:
In this paper a decoupled signed-distance fuzzy sliding mode controller is presented for overhead crane system. In industries, overhead cranes are commonly employed to lift and lower materials or to move them horizontally. Sliding mode control (SMC) is a special nonlinear control method which have quick response, insensitive to parameters variation and disturbance, online identification for plants are not needed, it’s very suitable for nonlinear system control. Fuzzy logic systems are used to approximate the unknown system functions and switch item. Stability of the proposed control scheme is proved by Lyapunov theorem and the control scheme is applied to an overhead crane system. The simulation results show the effectiveness of the proposed controller in coping well with uncertainties while ensuring asymptotic stability.
