Abstract
It is well-known that optimal Hankel-norm approximations are seldom unique for multivariable systems. This comes from the Hankel-norm being somewhat of a crude criterion for the reduction of multivariable systems. In this paper, the strengthened condition originated with N. J. Young is employed to restore the uniquess. A statespace algorithm for the computation of super-optimal solution is presented.
