Embodiment Construction

[0021] The technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments.

[0022] The invention provides a kiln temperature control method based on deep learning and reinforcement learning, which adjusts the valve openings of oxygen and natural gas in the kiln according to the set values ​​of each key temperature point, so that the temperature environment of the kiln remains stable. This method uses a deep neural network to establish a kiln temperature simulation model based on key characteristic quantities such as kiln historical temperature, pressure, natural gas and oxygen flow, and valve opening, which is used to simulate the kiln temperature change environment. Based on the temperature simulation model, according to the real-time environment of the current kiln temperature, pressure, fuel concentration, etc., combined with deep neural network and reinforcement learning algorithm, the kiln temperature control...

Abstract

The invention provides a glass furnace temperature control method based on deep learning and reinforcement learning. The method comprises the following steps: establishing a temperature simulation model and a temperature control model through a total-oxygen glass kiln furnace taking natural gas and oxygen as fuel, and maintaining the stabilization of the kiln temperature by regulating a fuel valve; collecting temperature, oxygen flow, natural gas flow, natural gas valve openness, natural gas valve opening and kiln pressure at each key point of the kiln through a sensor; establishing a kiln temperature simulation model by using a deep neural network, thereby simulating the kiln temperature change environment; establishing a kiln temperature control model based on the deep learning and reinforcement learning, and outputting the offset needing to be adopted by the natural gas and oxygen valves in real time according to the current furnace state by using two established models. By utilizing the historic kiln data, the temperature simulation model and the temperature control model are online or periodically updated, thereby reaching precise temperature control.

Description

technical field [0001] The invention relates to the technical field of temperature intelligent control of a glass melting furnace, in particular to a method for controlling the temperature of a glass melting furnace based on deep learning and reinforcement learning. Background technique [0002] The generation process of a glass melting furnace combines a large number of physical reactions and chemical reactions. If it is to be modeled, it will be a complex nonlinear system with many distributed parameters, and the process is very difficult, so it is difficult to control it precisely. At present, the method of controlling various parameters of glass melting furnaces in my country is single-loop PID control, and PID means proportional-integral-derivative controller. Traditional PID controllers are widely used in industry due to their effectiveness for linear systems, ease of design and low cost. Yamamoto and Hashimoto reported in 1991 that, for example, in Japan, more than 9...
