| Abstract: | The finite-time control problem for a class of discrete-time linear singular systems subject to norm-bounded exogenous disturbances is discussed. Firstly we analysis the problems of feasible solution and obtain the sufficient conditions that guarantee the problems discussed to be feasible solved. Secondly, the state feedback controller and output feedback controller are designed respectively. After that we can obtain the sufficient conditions to guarantee the closed-loop systems to be bounded in finite--time, which can be reduced to feasibility problems involving linear matrix inequalities （LMIs）. Linear matrix inequalities（LMI） in Matlab toolbox can be applied to get the solution. Finally, a numerical example is given to illus- trate the validity of this proposed method. |
