✦ Synopsis

The paper addresses an approach to robust stabilization of chemical continuous stirred tank reactors. State feedback was used for the stabilization and the feedback controller was designed using the robust model-based predictive control algorithm in which the symmetric constraints on input and output variables are taken into account. The known strategy was modified by adding integral action to the controller. Parameters of robust feedback controllers with and without integral action were found as solutions of a constrained optimization problem solved on the infinite prediction horizon. The possibility to stabilize chemical reactors with uncertainty using the robust modelbased predictive control has been verified by simulations and compared with the optimal linear quadratic control and the model-based predictive control. The obtained results confirm that the robust model-based predictive control provides better results than other approaches.

The nonlinear model of a continuous stirred tank reactor is shown to be flat. The flatness permits the design of suitable trajectories on the basis of the explicit stationary solution and the tracking of these trajectories asymptotically using quasi-static state feedback linearization.

The design of a robust non-linear feedback controller has been analysed for product concentration tracking in the case of parallel reactions occurring in a semi-batch isothermal reactor. Simulation results show the efficiency of the control scheme and its robustness to modelling errors.
