A control system for a gas turbine, wherein a number of regulators (24) generate respective control signals (P1-P6) selectable (25) to regulate (27) fuel supply to a combustion chamber (5) of the gas turbine. The regulators include at least one speed/load regulator, wherein a first and a second regulating block (60, 64), separate from each other, generate respective control signals which are selectable to perform speed control of the turbine and load control of the turbine.
