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。
In order to meet the requirements of ship network, information and intelligence, the control problem of fin stabilizer under the network of integrated management platform was studied. Based on the traditional fin stabilizer system model, a model of fin stabilizer network control system is proposed under the integrated management platform. The influence of induced delay induced by platform network on system performance is analyzed. Based on the mean value prediction method, a new kind of delay discriminator is designed by introducing the idea of “error prediction” in predictive control algorithm. On this basis, a new type of smith estimator is designed for the interaction between wave interference and network delay. The theoretical analysis and simulation results show the effectiveness of the delay estimator and smith predictor.
