Abstract
This paper describes the development of a simple sliding mode controller (SMC) and a relay enhanced multi loop PI controller for multi input multi output (MIMO) processes. In the decentralized SMC design, convergence property of the closed-loop system is guaranteed by means of satisfying a sliding condition. For relay-enhanced design, the control system employs a relay in series with the controller, which yields oscillations for tuning of the PI controller based on an equivalent process model for each loop. Simulation studies are carried out on a two-input-two-output (TITO) process to illustrate the effectiveness of the two methods and to compare their performances. The performance of the controllers is compared also with that of the existing methods.
