Patent ID: 7310981

Claim:
A method of controlling a temperature of strip metal processed in a finishing train of a technical installation, the method comprising: comparing a target temperature gradient to an actual temperature gradient associated with the strip metal, the actual temperature gradient including a point temperature gradient determined for a number of individual local points of the strip metal; determining a target function for at least one actuator having adjustment limitations, the actuator arranged in the finishing train, the target function determination based on the target temperature gradient, the actual temperature gradient, the adjustment limitations of the actuator, and the point temperature gradient for adjusting the actuator and controlling the temperature; adjusting the actuator based on the target function so that the actuator is controlled via a control variable corresponding to a flow of cooling agent or a flow of material in order to control the temperature; and calculating adjusting signals for adjusting the actuator by solving an optimization problem represented by the target function and the side conditions.
