An Exponent-Logarithmic Terminal Sliding Mode Control for Uncertain High-Order MIMO Systems

In this paper,an exponent-logarithmic terminal sliding mode control scheme is presented for a class of uncertain high-order MIMO systems.An exponent-logarithmic nonlinear sliding surface is proposed such that the states along the specified sliding surface attain the equilibrium point in finite time with a faster convergence rate.Moreover,a sliding mode controller is designed to guarantee the finite-time reachability of the specified sliding surface.Finally,the simulation results illustrate the effectiveness of the proposed exponent-logarithmic terminal sliding mode control strategy.
