Abstract

A method (200) of controlling an operating temperature of a first combustion zone (115) of a combustor (106) of a rotary machine (100) includes determining a current operating temperature and a target operating temperature of a first combustion zone (115) using a digital simulation. The method (200) further includes determining a derivative (408) of the current operating temperature with respect to a current fuel split using the digital simulation. The fuel split apportions a total flow of fuel to the combustor (106) between the first combustion zone (115) and a second combustion zone (117). The method (200) also includes calculating a calculated fuel split (410) that results in a calculated operating temperature approaching the target operating temperature. The method (200) further includes channeling a first flow of fuel to the first combustion zone (115) and a second flow of fuel to the second combustion zone (117).
