The stabilization of a front pattern in a homogeneous tubular reactor model was studied. Linear stability analysis combined with the Galerkin method is used for state-feedback control of the distributed parameter system. The capabilities of the global control and point-sensor control to stabilize the front solution were studied by manipulating various reactor parameters, including fluid flow and feed conditions. Point-sensor control in coolant flow (heat-loss coefficient) or coolant temperature are the most effective when the temperature sensor is located close to the front position. Global control based on a space-averaged sensor and other strategies failed. A qualitative analysis is suggested for selection of proper control of front stabilization.
