报告摘要：

In this  talk, the positive realness problem in control theory is studied. A numerical method is developed for verifying the positive realness of a given proper rational matrix H(s) forwhich H(s) + HT (−s) has purely imaginary zeros. The proposed method is only based onorthogonal transformations, it is structure-preserving and has a complexity which is cubicin the state dimension of H(s). Some examples are given to illustrate the performance of the proposed method.
