Abstract: An analysis and control device for glass furnaces is of the fuzzy-controller type and uses a control algorithm which receives information relating to the operation of the furnace coming from sensors and from detection means provided on this furnace, as well as set point values input manually by operators. This control algorithm delivers control signals to the various actuators and control means of the furnace. A predictive system, of the neural- and/or fuzzy-type is included which depends on the state of the furnace and on the information about the change in production over time. It defines the various set point values to be assigned to all the furnace actuators, so as to ensure optimum operation for each production phase. The set point values constitute input values for the fuzzy-logic algorithm which controls the furnace.

Abstract: Device for controlling the melting of the glass batch in a glass melting furnace, which automatically carries out all or some of the set of operations for controlling the operating parameters of the furnace as well as all or some of the set of operations for operating the furnace actuators, on the basis of the strategies that an operator carrying out these operations manually would employ, this device comprising:

Abstract: Procedure for regulating the heating of a furnace implementing a conventional means of regulation and a fuzzy logic supervisor which, on the basis of the given situation and the information which it receives on its inputs, adapts the parameters of the regulator, wherein the procedure includes the following steps:detection of the state of the process to be controlled and regulated;transient state or steady state is selected depending on the instructions/measurement discrepancy;selection of a control algorithm on the basis of the state (transient state or steady state) with the aid of a toggle based on the principle of fuzzy logic, while ensuring a smooth changeover between the states, with no discontinuity of control; andcalculation of the parameters of the regulator on the basis of the specific requirements, taking into account the following factors: volume production and rate of production, i.e., of the mass of the products treated in the furnace and of the speed of production; and temperature of the charge.
