Abstract: To address the challenge of suppressing low-frequency line-spectrum vibrations in mechanical equipment such as the main and auxiliary machinery of underwater vehicles, this paper proposes a DFOFxLMS(dual-channel fractional-order filtered-x least mean square) algorithm based on the fractional-order gradient descent method. The control performance of algorithms with different fractional orders is analyzed and compared through simulations. An experimental platform for active vibration control based on a floating raft–cylindrical shell structure is established. Comparative experiments under various operating conditions demonstrate that, compared with single-channel control strategies, the proposed dual-channel collaborative control scheme exhibits significant advantages in suppressing the overall vibration of the floating raft–cylindrical shell system. Furthermore, it demonstrates excellent engineering practicality and control effectiveness under dual-frequency line-spectrum disturbance scenarios. -
