| 1. A method for controlling a bypass air split for a gas turbine combustor comprising:
determining a target exhaust temperature, wherein the target exhaust temperature is based on at least one parameter of a group
of parameters consisting of low pressure turbine speed, high pressure turbine speed, inlet guide vane angle, and bypass valve
air split;
using the target exhaust temperature to calculate a required percentage of bypass air split based on maintaining maximum CO
levels or minimum NOx levels; and,
applying the required percentage of bypass air split to control a position of the bypass air valve.
