A pole‐placement self‐tuning controller has been used to control a fixed‐bed autothermal reactor conducting the water‐gas shift reaction at both an upper stable state and a middle unstable state. Excellent set‐point tracking and disturbance rejection characteristics were obtained using a single manipulated variable, the heat input at the entrance to the catalyst bed, to control a single bed temperature. Excellent set‐point tracking during the transition from the upper state to the middle state was obtained by using a technique that tuned the closed‐loop poles on‐line so as to give an optimal response.
