A system for controlling a propeller having a plurality of blades (12) having a primary control system (16) and a backup control system (25). The primary control system (16) including a sensor (29) responsive to a propeller state, and a controller (100) connected to the sensor and to an electrohydraulic control actuator (20). The electrohydraulic control actuator connected via a bypass valve (24) to a hydraulic actuator that controls at least a blade angle of a blade of the propeller. The controller generating commands to the electrohydraulic control actuator based on at least the propeller state. The backup control system including a second controller, an electrohydraulic solenoid operably connected to the bypass valve. The backup control system operable to hydraulically disable the primary control system via the bypass valve upon the occurrence of a selected condition, the second controller modulates the operation of the electrohydraulic solenoid to control the bypass actuator based on the propeller state.
