摘要

摘要: 船舶振动会产生全方位的干扰力, 这种干扰力会使重要设备产生结构疲劳, 从而影响使用寿命。为了减小这种干扰对设备的影响, 文中设计了一种应用于船舶的磁悬浮减振装置, 并针对水流、船体转向等不同干扰造成的托举失衡问题提出了基于自适应模型的预测控制方法, 该方法兼具自适应控制与预测控制的优点, 可以实时更新预测控制中的模型参数, 极大地提升预测控制的精确度。实验验证结果表明, 这种方法响应速度更快, 鲁棒性较强, 具有较强的抗干扰能力, 能够满足特种船舶重要装置的减振要求。

Abstract: Ship vibration generates different interference forces, resulting in the structural fatigue of important equipment and thereby affecting their service life. To reduce the impact of this interference on the devices, a magnetic suspension vibration reduction device is designed and applied to ships. A predictive control method based on an adaptive model to solve the problem of lift imbalance caused by different types of interference of water flow and hull steering is proposed in this paper. This control method is, therefore, adaptive and predictive. The model parameters in this predictive control can be updated in real time, greatly improving the accuracy of the predictive control. Finally, the results of relevant verifications show that this method has a faster response speed, stronger robustness, and strong anti-interference ability. Furthermore, it can be used to fulfill the vibration reduction requirements of important devices in special ships.
