摘要：
In practice, finite-time stability of systems is more practical and economical than the traditional stability due to costs and other constraints. This paper studies the finite-time stability and stabilization for a class of quadratic discrete-time systems. By means of linear matrix inequality, the design of feedback control gain matrix is converted into the solutions for linear matrix inequalities. Moreover, sufficient conditions for the finite-time stability of closed-loop systems with state feedback are determined, and a method to design the feedback control gain matrix is proposed to achieve the finite-time stability of systems. This method is also suitable to deal with the finite-time boundedness of systems with exogenous disturbance. Finally, numerical examples are used for validation. The consistency of simulation and theoretical analysis results proves the feasibility of the proposed method. ©, 2015, South China University of Technology. All right reserved.
