Abstract

The problem of constant L_∞, approximation of complex rational matrix functions is studied. A characterization of the solution is given. A suboptimal computational scheme, based on balanced realization for unstable systems, is developed, and corresponding error bounds are obtained. An L_∞ error bound for unstable systems is derived. Optimal solution for a class of symmetric systems is explicitly obtained.
