船舶综合管理平台网络下减摇鳍预估控制

Prediction Control of Fin Stabilizers under Ship Integrated Platform Management System Network

为满足船舶网络化、信息化和智能化的要求,研究了综合管理平台网络下减摇鳍的控制问题。在传统减摇鳍系统模式的基础上,提出了综合管理平台下减摇鳍网络控制系统的模型。分析了由于平台网络引入的诱导时延对系统性能的影响。以均值预测法为基础,引入预测控制算法中"误差预测"思想,设计了一类新的时延辨识器。在此基础上,对于海浪干扰和网络时延的共同作用设计了一种新型的smith预估器,理论分析和仿真研究表明了该时延辨识器和smith预估器的有效性。

To meet the requirement of network information and intelligent development of ship, the control problem of fin stabilizers un- der the ship integrated platform management system （IPMS） network is discussed. On the basis of the traditional system, a model of fin stabilizer networked control systems under IPMS is proposed. The effect on the system performance due to network delay is analyzed. A new delay identifier is designed based on the mean prediction and with the introduction of ＂ error forecasting＂ principle of predictive control algorithm. And a novel smith predictor is designed to control the ocean wave disturbance and network delay. The theory analysis and simulation results show the effectiveness of the proposed approach.
