摘　　要：基于LMI方法研究了Delta算子描述下的线性定常系统的H2控制问题,利用Schur补性质推导出状态反馈控制律存在的充分必要条件,用一个线性矩阵不等式的可行解给出了状态反馈控制律的一个参数化表示。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.
