    • A speed control system for an engine comprising at least one rotary load is provided. The speed control system may include a rotor speed controller configured to regulate speed in the rotary load based on a sensed rotor speed, exclusive of resonant mode speed oscillations, in closed loop feedback with a commanded rotor speed. To provide active damping of resonant mode speed oscillations, a resonance disturbance rejection controller may be configured to compensate a speed control signal by observing a component of the sensed rotor speed that is due to resonant mode oscillations. Based on the observed resonance component, the resonance disturbance rejection controller may compute an adjustment value for the speed control signal. In the particular case of gas turbine engines, the resonance disturbance rejection controller may effect active damping by compensation of a fuel flow request for a gas generator.
    • 提供了一种用于包括至少一个旋转负载的发动机的速度控制系统。 速度控制系统可以包括转子速度控制器,该转子速度控制器被配置成基于感测到的转子速度(不包括谐振模式速度振荡)来调节具有指令的转子速度的闭环反馈中的转速。 为了提供谐振模式速度振荡的主动阻尼,谐振干扰抑制控制器可以被配置为通过观察由于共振模式振荡而导致的感测转子速度的分量来补偿速度控制信号。 基于观察到的共振分量,共振干扰抑制控制器可以计算速度控制信号的调整值。 在燃气涡轮发动机的特定情况下,共振扰动抑制控制器可以通过补偿气体发生器的燃料流量请求来实现主动阻尼。

    • PROBLEM TO BE SOLVED: To control a gas turbine for maintaining an efficient operation state, by preventing operation from deviating from an operation state in an ideal fuel flow rate and air flow rate supposed in design.
      SOLUTION: This gas turbine control device is composed of a frequency analyzing means 13 in a combustor, a state grasping means 12 for grasping a combustion state based on an each frequency band analyzing result, an operation process quantity including the ratio of the air flow rate and pilot fuel and a state signal including an atmospheric state and a load quantity, a combustion characteristic grasping means 14 for grasping a characteristic of combustion vibration, and a control part 3 for driving by correcting an initial design value of the preset air flow rate and the pilot ratio in response to the operation process quantity and the state signal, by calculating at least one correction quantity of the air flow rate and the pilot ratio supplied to the combustor every time when the combustion vibration exceeds a predetermined management value from a combustion vibration characteristic and the combustion state. The control part 3 is operated by the initial design value by resetting a correction of the initial design value in a state where the combustion vibration becomes less than the predetermined management value by a specific time.
