In this work, we introduce a new structure for cascade control scheme based on a weighted average temperature of three-temperature measurement distributed along the axial position of the tubular reactor. The control configuration exploits the information provided by two additional temperature sensors located close to the feed and the output positions of the tubular reactor. The configuration with the averaged temperature improves the behavior of the classical cascade control scheme by enhancing the disturbance rejection. Numerical simulations of two axial dispersion models of tubular reactors are used to illustrate and compare the control performance.
