| Abstract: | The problem of H_2 control with Delta operator is formulated in LMI in this paper. A necessary and sufficient condition for the existence of H_2 state feedback controller is derived by using the Schur complement. It is showed that this condition is equivalent to the solvability problem of a group of linear matrix inequalities, and its solutions provide a parameterized representation of H_2 state feedback controller. |
