Abstract :
An "l∞-norm" version of the so-called "S-procedure losslessness theorem" is proved. In contrast with the earlier result which applies to robust control in the "mean squares" (H∞) setting, the new theorem establishes the non-conservatism of the Lagrange multipliers method for "maximum magnitude" models (the so-called l1-setting).
