The invention belongs to the technical field of helicopter rotor folding, and discloses a novel rotor electric folding and unfolding control system and method, and the control system comprises a folding controller, a main propeller collector ring, a disc propeller controller, four folding actuator cylinders, five support arm limiting locks, and a disc propeller mechanism. An angular displacement sensor is arranged in the main paddle collector ring; wherein the folding controller is respectively connected with the main paddle collector ring and the disc paddle controller through CAN buses, themain paddle collector ring is respectively connected with the four folding actuating cylinders and the five support arm stop locks through CAN buses, and the disc paddle controller is connected with the disc paddle mechanism through a CAN bus. A rotor wing electric folding mode is adopted, a rotor wing disc paddle, a locking mode and a paddle driving mode are all driven by a permanent magnet synchronous servo controller,
