In a tinplate line the coating thickness can be controlled by means of the line speed and current applied. A new system has been developed that calculates the maximum possible speed and the total necessary current, distributing it into the available rectifiers. The equations used for the calculations are based on a mathematical model obtained using Genetic Programming.
