MODEL PREDICTIVE CONTROL OF A TUBULAR AMMONIA REACTOR-HEAT EXCHANGER SYSTEM WITH SQUARE AND NON-SQUARE CONTROL STRUCTURES USING SINGULAR VALUE DECOMPOSITION (SVD)
Part II: Application to an Ammonia Reactor-Heat Exchanger System
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.
