Methods for Controlling Actuating Components of Turbine Engines Using an Adaptive Damping Filter

Abstract:

Methods for controlling actuating components of turbine engines using an adaptive damping lag filter are provided. The adaptive filter includes features that filter out insignificant changes in actuator demand, respond to fast transient conditions to follow demanded position of the actuating component more closely, and adapts the gain of the output position to avoid stall conditions.
