This paper derives a rank type formula for the computation of the singular value equation arising in the H∞ problem with infinite-dimensional unstable plants. It is based on an extension of the skew Toeplitz approach for the stable plant case. Similarly to the stable plant case, parametric representations of the singular value equation plays an essential role. An example is given to illustrate the result.
