Controle de engenharia de processos integrado ao controle estatístico

Abstract

This paper deals with the modeling and control of a boiler for the transport of heat. Control applied is based on the integration of two distinct forms of process control, Statistical Process Control through the control chart Moving Averages Exponentially Weighted, and the Control of Process Engineering, more specifically with the PID controller. Are presented three different scenarios, coupled to three typical ways of operation that the boiler studied. Each scenario are compared the behavior of the variables controlled for each type of control applied to such was employed numerical simulation. The results are evaluated visually through the simulations presented and measured by the mean square error.
