Abstract

In this paper, we present the application of a model predictive control (MPC) strategy to a tubular ammonia reactor-heat exchanger system based on the singular value decomposition (SVD) approach to computation of the control law. The SVD-based MPC controller was used to evaluate various ,  and  structures under nominal, additive plant/model mismatch, and measurement noise. The closed-loop simulation results validated the previously reported outcome of the selection of the most promising  and  control structures, and rejection of the control structures based on dynamic resilience analysis. The designed SVD-based MPC controllers performed better than a decentralized PI controller previously reported in the literature.
