Abstract
A method for coating a metal strip using a coating metal, in particular for coating a steel strip using zinc or a zinc/nickel compound, by means of at least one electroplating cell through which current flows and which contains an electrolyte through which the metal strip is passed, the current effecting the deposition of a layer of coating metal on the metal strip, and the current being controlled by a so-called monitor controller that has a process model and a controller part. The current is controlled in such a way that a layer of a desired thickness is deposited on the metal strip, the controller part being adjusted to the altered state of the coating plant in the event of changes in the state of the coating plant, in particular when a new metal strip enters or the coating falls below a minimum intended layer thickness.
