  • Abstract
    A novel smooth second order sliding mode controller based on a modified “twisting” algorithm for relative degree two systems is discussed to provide robustness as well as accuracy. A robust exact observer is introduced in the closed loop system to reject the drift signals. A Lyapunov method combined with homogeneity concept is used to prove finite time stability of the overall system. The method is verified through simulations on a benchmark example of a DC motor.
