Abstract :
In this paper, negative imaginariness for descriptor system is studied. The Negative Imaginary Lemmas for standard linear time-invariant system are extended to descriptor system where the transfer function G(s) is divided to two cases: the origin is a pole of G(s) or not. Two numerical examples are presented to illustrated the efficiency of the proposed methodology.
