Research on temperature uniformity optimization of microwave heating Debye media based on MDADT

Abstract

In the microwave heating process, the uneven temperature distribution is not conducive to improving the quality characteristics of the media. This article proposes a model-dependent average dwell time (MDADT) switching control method for the uneven temperature distribution of the Debye medium during microwave heating. First, a mathematical model of microwave heating switching control is established. Next, according to the mathematical model, the sufficient and necessary conditions for Lyapunov stability in the MDADT microwave heating process are given, which enables the microwave input power to coordinate with the model-dependent average dwell time. Last, numerical simulations of microwave heating SiC show that the proposed method can improve the temperature uniformity of the media and reduce the energy consumption, which indicates the effectiveness of the proposed method.
