電気炉温度制御における最適多段供給電圧

Abstract

This paper is about the problem of determinating multistage supplying voltages optimally which are power source for a small electrical reheating furnace in its temperature control. The state transition equation is approximated by first order difference equation and the performance index is given in form of the summation of the square error, that is, the difference of reference value and temperature inside the electrical furnace. Our aim is to determine the multistage supplying voltages as optimum control policy in order to minimize the given performance index and to apply this optimum control policy experimentally to temperature control of small electrical reheating furnace. We obtained good results in comparison between experimental curve and computational one, as shown in some figures.
