Abstract: A control method, system and device for a flexible carbon cantilever beam actuated by a smart material is provided. The new control method, system and device aims to solve the problems of control overflow and instability that are likely to occur in the distributed parameter system constructed in the prior art. The method includes: acquiring an elastic displacement of the flexible carbon cantilever beam in real time as input data; and obtaining, based on the input data, a control torque through a distributed parameter model constructed in advance, and performing vibration control on the flexible carbon cantilever beam. The new control method, system and device improves the control accuracy and stability of the distributed parameter system.
