Abstract

This work proposes a Generalized Predictive Control (GPC) with three steps ahead for plant controller and Proportional Integrative Derivative (PID) control, using the Extended Least-Squares algorithm for the plant identification. As a result we have a low-cost solution and easy implementation for electrical ovens, in this case, power of 2500W. Both control application had gotten a variation about 0.2% around the setpoint at steady-state, which is acceptable because ±2ºC in thermal treatments can produce reliable results. Also, this error is much better if you compare with manual process that gets an error from 20 to 30%. GPC shows faster convergence to set-point than PID control because it happened in about 1740s, while 8230s for PID control.
