The invention relates to a current protection strategy for a bipolar direct-drive-valve actuator, which is used for controlling a force motor state of a servo controller in a flight control system. The current protection strategy for the bipolar direct-drive-valve actuator comprises the following steps of 1, signal obtaining; 2, signal processing and decision; 3, current protection starting condition judging; and 4, current protection condition judging. Through adoption of the current protection strategy for the bipolar direct-drive-valve actuator, current protection starting of the servo controller can be automatically finished when an airplane is in ground maintenance; therefore, phenomenon that a force motor of the servo controller fails to work because servo current protection is not started due to manual misoperation or forgetting is avoided; the safety of the current protection of the servo controller is ensured; the maintenance efficiency is increased; and requirements of outfield maintenance and infield maintenance of the airplane flight control system are satisfied.
