Claim:
1. A method for use in transferring between combustion modes during operation of a gas turbine engine, said method implemented using a computing device including a processor coupled to a memory device, said method comprising: receiving, by the computing device, real-time sensor data from at least one sensor coupled to the gas turbine engine; generating, by the computing device using the real-time sensor data, data representative of an initial set of splits for providing at least one of fuel and air to at least one combustor in the gas turbine engine; generating, by the computing device using the real-time sensor data, a model of the gas turbine engine, wherein the gas turbine engine model generates as an output data representative of at least one operating condition within the gas turbine engine; operating the gas turbine engine in a first combustion mode using at least one set of active control splits; generating, during operation of the gas turbine engine in the first combustion mode, by a first split calculation module within the computing device using the model output data and the initial split data, data representative of the at least one set of active control splits for use in controlling the gas turbine engine in the first combustion mode; generating, during operation of the gas turbine engine in the first combustion mode, by at least a second split calculation module within the computing device using the model output data and a feedback signal selected from at least one set of passive control splits, data representative of the at least one set of passive control splits associated with at least a second combustion mode of the gas turbine engine; and transferring, by the computing device, operation of the gas turbine engine to the second combustion mode using the at least one set of passive control splits generated during operation in the first combustion mode.
