【摘要】In this paper, a class of similar composite systems is discussed, whose interconnections areasymmetrical and mismatched. The interconnection

condition

is

proposed.

Based

on

it,

the

interconnectionsare divided into two parts. One satisfies the interconnection condition, by means of the two--step method,the decentralized controllers are designed. The other does not satisfy the interconnection condition, but thisis offsetted by good quality of the system itself. Based on these, a sufficient condition is given by some linearmatrix inequalities, which makes the studied systems quadratic stabile via linear decentralized controllers bymaking use of the information of interconnections better. 【总页数】11页(62-72)
