摘要： Engine control systems utilize a number of potential control loop regimes optimized 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, such as squaring of the error divergence, in order to retain authority for the transient control loop control beyond the normal selector determined error divergence criteria.

摘要： Systems and methods for detecting and accommodating for loss of a torque signal of a gas turbine engine are described herein. An engine deterioration offset may be determined while the torque signal of the engine is available. Then, in the event that the torque signal is lost, a predicted operating offset may be determined. A synthesized torque signal may be generated when the torque signal is lost at least in part from the engine deterioration offset and the predicted operating offset.
