An Improved MPC Algorithm for the Multitubular Fixed-Bed Catalytic Reaction Process

Model predictive control (MPC) is a widely used control technique in chemical processes due to its simple principle and its clear effectiveness in controlling difficult-to-control processes, including those with delays and interference. In this paper, we developed an improved MPC algorithm that can be reasonably applied to catalyst bed temperature control in the multitubular fixed-bed catalytic reaction process, a widely used process in the chemical industry. We verified its effectiveness through simulations.
