The german "Betragsoptimum" is apparently called "modulus optimum" in english

In my German courses on electrical drives, they taught us that the Betragsoptimum method for tuning a control loop, where the controlled system has one "dominant" time constant (higher or larger than all others), which is compensated/cancelled directly by the controller.

Though difficult to find on the Google WORLDWIDE-INTERNET-WEB®, this seems to be called modulus optimum (or, perhaps also "absolute value optimum").
