QFT-Based Robust Simmering Control for Domestic Induction Cookers Using an Infrared Sensor

This paper presents a robust simmering control for induction hobs. This kind of process is almost impossible to carry out in a domestic cooker where the pot temperature is unknown. We exploit an analytical model of the cooking process to design a QFT-based controller. The resultant controller satisfies all user requirements such as a quick heating up, an accurate temperature control and a fast disturbance rejection. Additionally, the proposed temperature control can also minimize the energy consumption and, as a consequence, it can increase the efficiency of the cooking process. Finally, the effectiveness of our proposal has been verified by means of verification test in real induction hobs.
