Control system
An output control system for a gas turbine, comprising a fuel flow control valve provided in the fuel supply circuit of the gas turbine for continuously regulating the flow rate of the fuel to be supplied to the combustor of the turbine, and a control circuit for operating the valve to enable the gas turbine to produce a constant output speed, the control circuit including a proportional-plus-integral action network for producing a signal variable with the output speed of the gas turbine, load-change detecting means responsive to an abrupt change in the amount of load on the gas turbine for producing a signal representative of such a change, and an integrator output modifier responsive to the signal from the load-change detecting means for modifying the output signal from the integrator in the proportional-plus integral action network in such a manner that the delay in the response of the integrator to an input signal is eliminated or at least reduced to a minimum.
