Abstract
This paper presents a brief study of concepts used in control of two-input and two-output systems. A novel decentralised model predictive control (DMPC) for two-input and two-output (TITO) processes is presented. To reduce the computational load, shifted input sequence is used to cater for loop interactions. The proposed scheme is applied to a coupled system to demonstrate its performance. Model predictive control (MPC) and decentralised proportional, integral and derivative (PID/PI) controllers were also applied for comparison purposes. The proposed controller has a performance similar to MPC but outperforms the decentralised PID/PI controllers.
