    摘要： In a fuel control system (10) for a gas turbine engine (1) having a gas generator (4) and a turbine (6) driven by the gas generator (4): a main fuel regulator (12) determines a demand (W f dem) of fuel flow (W f ) to be introduced in the gas turbine engine (1), based on an input request (PLA); and a first limiter stage (14), operatively coupled to the main fuel regulator (12), causes an adjustment of the fuel flow (W f ) based on engine safety operating limits. The first limiter stage (14) is provided with a Ngdot limiter (20) to cause an adjustment of the fuel flow (W f ) when the gas generator speed rate of change (Ngdot) is determined to overcome acceleration/deceleration scheduled safety limits; the Ngdot limiter (20) implements a predictor (23), to perform a prediction ( W f dot ) of the fuel flow rate of change (W f dot), or fuel flow (W f ), allowing the gas generator speed rate of change (Ngdot) to track a scheduled reference value (Ngdot ref ).

    摘要： The method according to the invention comprises, during a phase (EO) of starting up the turbomachine : — a step (E10) of open-loop generation of a control (WF_OL) of the flow of fuel based on at least one pre-established law; and — a step (E20-E30) of closed-loop monitoring of at least one operating parameter of the turbomachine selected from: o an acceleration rate (dN2/dt) of a compressor of the turbomachine, and o an output temperature (EGT) of a turbine of the turbomachine, this monitoring step comprising keeping (E30) the operating parameter within a range of predefined values, using at least one corrective network (R1, R2, R3) associated with this parameter and capable of providing a correction signal correcting the fuel flow control generated in an open loop manner, making it possible to keep the operating parameter within the range of predefined values.

    摘要： A method for controlling a gas turbine when the gas turbine is started may include measuring the number of rotations of the gas turbine, determining a target acceleration rate based on the number of rotations of the gas turbine, measuring a current acceleration rate, determining a flow rate of fuel based on a difference between the current acceleration rate and the target acceleration rate, and supplying fuel to the gas turbine at the determined flow rate. The flow rate of the fuel may be determined between a maximum flow rate of the fuel that has been previously stored and a minimum flow rate of the fuel. A temperature of the exhaust gas after controlling the flow rate of the fuel may be monitored.

    摘要： Engine control arrangement utilise a number of potential control loop regimes optimised for particular engine conditions. These loops may relate to transient conditions or engine steady state. The choice of engine control loop is made by a selector by the error divergence between measured signals and reference signals. These reference signals generate adjustment demands for the engine. It is possible for the nature of the selector to select the steady state control loop prior to acquisition of the desired target performance criteria. The steady state control loop will take longer to achieve the optimum performance conditions. The present invention provides for a multiplier (16), such as squaring of the error divergence (15), in order to retain authority for the transient control loop control beyond the normal selector determined error divergence criteria.

    摘要： Fuel control systems for use with a gas turbine engines which accounts for real-time thermodynamic engine effects when attempting to match or track the NDOT Actual rate to the NDOT Demand rate. The fuel control system includes a mechanism for measuring several engine operating parameters and a mechanism for determining an initial engine fuel demand based on the measured engine operating parameters. The control system further includes a mechanism for estimating, during engine operation and based on the measured operating parameters, the amount of heat transferred between fuel combustion gases and the engine metal and estimating an effective fuel flow adjustment based therefrom. The control system disclosed herein also includes a mechanism for determining a final engine fuel demand based on the initial predicted engine fuel demand and the estimated effective fuel flow adjustment.
