The relation is explored between linear feedback laws chosen to reduce the sensitivity of a linear time-invariant system to plant parameter variations, and linear feedback laws derived on an optimal control basis from quadratic loss functions. A general equivalence between the two types of design is established for multiple-input, multiple-output systems. The sensitivity improvement can be calculated for optimally design systems, and a quadratic loss function can be found for a system designed to reduce the sensitivity to plant parameter variations.
