SYSTEM AND METHOD FOR PROPELLER SPEED GOVERNING

Systems and methods for governing the speed of a propeller (120) on a propeller-based engine (110) in an aircraft comprise obtaining a synthesized or estimated blade angle (β) for the propeller (120) of the engine (110), determining one or more gain for a controller (204) of the propeller (120) based on the synthesized or estimated blade angle (β) and one or more engine or aircraft parameter (P1, P2), determining a difference between a reference propeller speed (Np) and an actual propeller speed (Np), applying the one or more gain to the difference via the controller (204) in order to generate a command signal (C) for controlling the propeller (120), and governing the propeller (120) of the engine (110) using the command signal (C).
