【Abstract】 In this paper,the fast terminal sliding mode control for a class of singular systems is studied.The singular systems are transformed into restricted equivalent forms by a nonsingular linear transformation.By the method of Lyapunov function,a novel exponential fast terminal sliding mode control strategy is proposed.A special exponential terminal sliding mode hypersurface is given and a controller is designed correspondingly,such that the asymptotic stability of the closed-loop system is guaranteed,the motion of sliding mode is realized,and the system state variables can converge to the equilibrium point with a fast convergence rat in finite time.Finally,a numerical example is presented to illustrate the feasibility and effectiveness of the design.更多还原
