Envelope Correspondence and Its Application to the Design of Guaranteed Error Controllers

In this paper, various problems of minimax error regulation are solved via the method of “envelope correspondence.” Using the Fenchel–Rockafellar system of conjugacy correspondence, we define a transformation
