Ambiente educacional multifuncional integrado para sintonia e avaliação do desempenho de malhas industriais de controle

Abstract

Industrial processes as well as the production based on the philosophy of quality assurance demand controllers that work facilities with their finely parameters, independent of the load situations and disturbances. A lot has been spoken regarding the PID controllers tuning, however, still, most is used in way PI or they possess adjusted parameters in an inadequate way, fomenting, like this, a premature life of the actuators and other components of the system. The control theory already studies controllers with PID algorithm since the beginning of last century, and several works prove controller PID’s efficiency for the classic and advanced control. In spite of PID controller to be used and studied at a long time, the acting of industrial loops is not satisfactory in many of the cases. Several criteria and acting indexes exist (IAE, ITAE,ISE, ITSE, Harris Índex, time of stabilization, etc.) that allow to define the efficiency of a control loop. Comes in this work an environment multifunctional, developed in C++, platform C++Builder, for tuning and analysis of acting of simulated industrial processes or real processes. This environment can also be used in the training of actual plant technical staff.
