The invention discloses a stability augmentation control strategy based on a wind-wave combined unit, and belongs to the field of ocean energy utilization. Aiming at the problems of improving stability and wind wave resistance of a large floating type offshore wind turbine in the prior art, dimension reduction and decoupling are carried out on a wave field by utilizing a dynamic mode decomposition algorithm, and a dominant wave mode is extracted in an optimal interval of relative movement of a floating body and is used for constructing an order reduction model; and finally, predicting the wave dynamics based on the development trend of each modal component in the reduced-order model. And locking and releasing the floating body under a proper wave surface condition according to the motion response of the platform so as to timely obtain energy or adjust the attitude of the unit.

    本申请公开了一种基于风‑浪联合机组增稳控制策略,属于海洋能利用领域。针对现有技术中存在的大型漂浮式海上风机提升稳定性及抗风浪能力的问题,本申请中,利用动态模态分解算法对波浪场降维解耦,在浮体相对运动最优区间内提取主导波浪模态,并用于构建降阶模型,最终基于降阶模型中各模态分发展趋势预测波浪动态。根据平台运动响应,在适当波面条件下锁放浮体以适时获能或调整机组姿态。
