Abstract
(EN) A method for controlling a heated process of an electric heater includes obtaining a setpoint variable indicating a target temperature of the heater. The method includes identifying an energy profile for the heater based on the setpoint variable. The energy profile provides a defined magnitude of initial electrical energy to be applied to the heater to have a temperature of the heated process reach the target temperature. The method includes obtaining a process variable indicating a performance characteristic of the heated process. The method includes providing electrical energy to the heater based on at least one of the energy profile and the process variable.
(FR) Procédé de commande d'un processus chauffé d'un dispositif de chauffage électrique comprenant l'obtention d'une variable de consigne indiquant une température cible du dispositif de chauffage. Le procédé comprend l'identification d'un profil d'énergie pour le dispositif de chauffage sur la base de la variable de consigne. Le profil d'énergie fournit une amplitude définie d'énergie électrique initiale à appliquer au dispositif de chauffage pour avoir une température du processus chauffé atteignant la température cible. Le procédé comprend l'obtention d'une variable de processus indiquant une caractéristique de performance du processus chauffé. Le procédé consiste à fournir de l'énergie électrique au dispositif de chauffage sur la base d'au moins un élément parmi le profil d'énergie et la variable de processus.
