Abstract:
1. A method for controlling an induction heating system of a cooking appliance provided with an induction coil and for controlling the induction heating system in connection with a predetermined working condition, the method comprises the steps of: measuring the value of at least one electrical parameter of the induction heating system; feeding a computing model a value representative of an actual switching frequency signal in order to estimate a temperature indicative of a thermal status of the heating system and to provide an estimated value of the electrical parameter; comparing the measured electrical parameter with the estimated one, wherein the electrical parameter is a current circulating in a primary circuit of the induction heating system; and tuning the computing model on the basis of such comparison, wherein the step of tuning the computing model includes the following differential equation: where: C → equivalent capacitance of the primary circuit; R L L M → equivalent mutual inductance; R V i i R T T α → A dimensional parameter.
