The sensitivity function in a generic two-degree of freedom (TDOF) control system can be decomposed into three major parts: design-, realizability- and modeling-loss. This decomposition opens new ways for practical optimization of TDOF systems and helps the construction of new algorithms for robust identification and control. The paper investigates the optimality of the second term in different norm spaces.
