Sintonia do controlador de uma válvula de dosagem de cinza seca em um moinho de cimento

Abstract

The manufacture of cement requires effective management of routine and precise control of product quality. Each type of cement is made by different measurement of materials, in quality and quantity , the development of this work was motivated by the need to minimize the quality deviations generated by detuned Proportional - Integral –Derivative (PID)controller, that is responsible for controlling the valve that makes the dosage of a additive to cement, fly ash within a cement mill. A variation on this dosage is directly reflected in consumer satisfaction, changing the properties of the product and cause instability during the grinding operation. According to the transfer function of the system and controller was possible to tuning the cement mill process and validate this.
