The objective of this paper is to design the autothermal reformer (ATR) temperature control by using a coefficient diagram method (CDM). The adiabatic temperature is a main controlled variable of the ATR which is a combination of endothermic and exothermic reactions. The simulation results of control parameters were calculated to maintain the ATR reaction temperature by manipulating air feed flow rate. In this work, two strategies of ATR temperature controller system with and without the feed temperature control of a preheater unit are compared to investigate the appropriate controller system when the change of surrounding temperature is considered as a key disturbance. The results showed that by using the CDM, the stability and robustness for controlling the ATR temperature system were considered to offer the proper control parameters and the designed temperature control of ATR system gave a good performance to maintain the controlled variables and reject the disturbance. Moreover, the ATR control system design with the feed temperature controller can compensate the surrounding temperature better than that without the feed temperature control.
