Abstract	FCCU plays the most vital role in modern refinery process because it has been used for producing more economic refinery products. The implementation of control algorithms for such MIMO system is often complicated due to continuous variations in process dynamics. This is mainly due to the change in operating point and the characteristics of nonlinear dynamic coupling. Since the conventional PID controller is a linear controller, it is efficient only for a limited operating range when it is applied to a nonlinear process. MPC controller can control highly interactive system s with many control variables and most importantly , MPC provides a systematic method of dealing with constraints on inputs and states. The proposed controller aims to maintain desired temperature of reactor and regenerator sections of fluid catalytic cracking unit. The proposed scheme offers good dynamic performance than GA tuned PID controller
