[0002] A resistance furnace is an electric furnace for industrial use, mainly used for high-temperature treatment and heat treatment. It is usually made of a high-temperature heat-resistant metal alloy that can withstand heating and high temperatures. A resistance wire or a resistance heating element is placed inside the resistance furnace. The resistance heating effect generated by the current passing through the resistance wire or the resistance heating element converts electrical energy into heat energy to heat the internal space of the resistance furnace. It is usually equipped with a temperature sensor and a control system to precisely control the internal temperature. The resistance furnace is often used to anneal medicinal packaging glass products such as pre-filled syringes, so that physical indexes such as stress of the annealed glass products meet the production requirements. During the annealing process, the temperature of the resistance furnace needs to be controlled. Due to the characteristics of the controlled object such as nonlinearity, large lag, and parameter uncertainty, the existing PID controller designed for a single temperature control quantity cannot meet the annealing requirements in terms of the control accuracy of the annealing temperature of the resistance furnace. There are problems such as uneven temperature distribution in the resistance furnace, untimely temperature adjustment, poor anti-interference ability, slow response speed, and low control accuracy, resulting in the inability to meet the annealing requirements for the control accuracy of the annealing temperature of the resistance furnace, making the glass products in different regions prone to uneven heating during annealing, which in turn leads to unqualified heat treatment, affecting the annealing effect of the glass products, and the unqualified pass rate of the glass product annealing.
