Gas turbine controller and a method for controlling a gas turbine

Method for transient operating of a gas turbine (1) and controller system (30) configured to carry out such a method as well as a gas turbine (1) comprising such a control system (30), where the controller (10) determines command values for an inlet air mass flow, fuel mass flow, and if applicable for a water or steam mass flow. In order to allow fast transient operation with a stable premix flame at least one command value is dynamically compensated in order to compensate for the different system dynamics of the supply systems in order to synchronize the resulting changes in fuel, water, steam, and/ or combustion air mass flows, which reach the combustor (3), so that the fuel to air ratio stays within the combustible limit.
