One possible approach to developing processes that are environmentally friendly and economically competitive at the same time involves the effective use of modern control technology to enable the operation of the process below the environmental constraints but close to them. However, often due to nonlinearities in the process, the performance of linear control strategies degrades as the system is operated close to constraints. Addressing these issues in the context of the specific process of fluidized bed catalytic cracking is the motivation behind the present paper. Such a study can help in the understanding of how process nonlinearity might restrict the effectiveness of linear control strategies and thus provide motivation for nonlinear strategies.
