Abstract

A method for controlling a variable-pitch propeller (24) of an aircraft (12) includes using a feedback controller (62, 76), operating the variable-pitch propeller (24) at a current operating condition including a current rotational speed (NPf), determining a speed error (E) between the current rotational speed (NPf) of the variable-pitch propeller (24) and a set point rotational speed (NPref) for the variable-pitch propeller (24), determining a gain (Kp, Kd) for the feedback controller (62, 76) based on a power coefficient (Cp) and an advance ratio (J) of the variable-pitch propeller (24). Using the feedback controller (62, 76), a propeller pitch command (Co) is determined based on the speed error (E) and using the gain (Kp, Kd). The pitch of the variable-pitch propeller (24) is adjusted according to the propeller pitch command (Co) to reduce the speed error (E).
