1. A method for obtaining, on the basis of a characteristic map, a value for at least one control parameter of an installation, the method which comprises:

  • defining support points for the control parameter, each of the support points providing a value for the control parameter, across a range of operational parameters within a characteristic map in accordance with operational parameters of the installation;

    dividing the range of operational parameters covered in the characteristic map into first and second subdomains each comprising a plurality of the support points;

    storing the characteristic map in a control device that controls the installation;

    using the control device to obtain a value for the control parameter by extrapolating when a boundary of the first subdomain is reached before the value for the control parameter is obtained by accessing support points of the second subdomain; and

    wherein the control device uses the control parameter to control the installation.
