Neuro-PID control of an industrial furnace temperature

In this paper, temperature control of a batch tank in a glass factory is investigated. In a turbo-generator system a large amount of energy is wasted as thermal energy at the exhaust. Therefore, use of combined heat and power (CHP) systems is highly under attention. In this work a turbo-generator system and a glass factory are considered as a CHP system. Since the hot exhaust gas has emissions which have a bad effect on the quality of molten glass, therefore, the hot exhaust must be used indirectly in melting glass process, so a rotary regenerator is proposed to transfer gas turbine exhaust heat to the inlet air of the glass melting furnace. It is assumed that turbo-generator is operated at full load condition and gas turbine exhaust is directed into rotary regenerator to transfer gas turbine exhaust heat to inlet air of glass furnace. By controlling the speed of the rotary regenerator, the amount of exchanged energy is controlled. An adaptive control strategy, namely, neuro-PID controller is proposed in this paper. The simulation results depict the capabilities of the proposed controller in different working states.
