NOVÁK, Z. and J. KYNCL. Real time optimization of temperature field in induction heating. Journal of Electrical Engineering. 2019, 70(5), 386-392. ISSN 1335-3632. DOI 10.2478/jee-2019-0070.
Many induction heating processes must be controlled in accordance with the prescribed time evolution of temperature of the heated body (bodies). This requires a correct setting of field currents (amplitudes and frequencies) in the heating inductors that can vary either continuously or by steps. The paper presents a novel model of induction annealing of cylindrical aluminum billets based on solution of nonstationary forward and inverse tasks. The methodology is described in detail and illustrated with a typical example. Some of the results were verified experimentally.
