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.
