@@@@In this paper, the finite-time control problem is considered for discrete linear sin-gular systems by virtue of Lyapunov’s method. The su?cient conditions for the finite-time stability of the open-loop discrete linear singular systems are given. Based on the conditions, a state controller is designed and the su?cient conditions for the finite-time boundedness of the closed-loop system composed by the state controller and the discrete linear singular system are presented. In particular, we consider a discrete linear singular system subject to an ex-ogenous output, and provide a designing method of controller and the su?cient conditions for the finite-time boundedness of the closed-loop system composed by the controller and discrete linear singular system subject to an exogenous output. Finally, a numerical example illustrates the validity of the proposed approach.
