Abstract

Industrial furnace is characterized by a time delay and slow response. Therefore, PID controller is commonly used for temperature control, due to its stability and easy installation. However, with PID, we have to refine PID parameters corresponding to different control cases, or variability of process parameters. Moreover, an issue arises in PID controller is how to set constraints for controller signals. For those issues, this article proposes a method based on Model Predictive Control (MPC) for improving performance of the controller and capability to adapt to different temperature objects, as well as control signal constraints. Simulation results of MPC control are compared with the results of PID in terms of performance indices, especially overshoot, response time for different set point values. It is observed that MPC for temperature process control provides better performance indices.
