报告摘要：The negative imaginary systems regarded as a class of LTV systems having a negative imaginary frequency response arise in many practical areas, such as lightly damped and undamped flexible structures. The negative imaginary property of negative imaginary systems may be seen as a generalization to the case of dynamic systems, of the negative definite property of matrices, where the imaginary part of the system transfer function matrix is considered. A In this talk, we give a generalized definition of irrational operator-valued negative imaginary functions using the complex symmetric operator，together with the negative imaginariness characterized by the conditions of imaginary axis and a condition at infinity. In addition, we present some spectral properties of negative imaginary functions.
