A method of controlling a startup sequence of a gas turbine. A turbine of the gas turbine may include a rotor that has a rotor velocity and a rotor acceleration during the startup sequence. The method may include the steps of: determining an originally scheduled startup duration for the gas turbine; measuring an intermediate rotor velocity at an intermediate time within the startup sequence; determining a recalculated remaining startup duration that is a duration calculated as necessary to achieve the final rotor velocity given the intermediate rotor velocity; determining a remaining portion of the originally scheduled startup duration based on the intermediate time; calculating a time multiplier based on a comparison of the recalculated remaining startup duration to the remaining portion of the originally scheduled startup duration; and scaling the rotor acceleration per the time multiplier for a duration until the final rotor velocity is achieved by the turbine.
