Abstract:This paper is concerned with the H infinity model reduction for negative imaginary (NI) systems. For a given linear time-invariant system that is stable and NI, our goal is to find a stable reduced-order NI system satisfying a pre-specified H infinity approximation error bound. Sufficient conditions in terms of matrix inequalities are derived for the existence and construction of an H infinity reduced-order NI system. Iterative algorithms are provided to solve the matrix inequalities and to minimize the H infinity approximation error. Finally, a numerical example is used to demonstrate the effectiveness of the proposed model reduction method.
