Abstract :
A parametrization is presented of all solutions to the 4-block H ∞ control problem with infinite and finite jω-axis zeros. The parametrization is given in terms of linear fractional transformation on stable transfer function matrices with gain less than 1, which are free apart from satisfying certain interpolation conditions
