摘　　要：碳纤维角联织物因其轻质、高强、耐腐蚀等优异特性,可以作为复合材料的增强结构骨架,在各个领域广泛应用。针对碳纤维角联织机经纱张力控制的精度问题,提出基于事件触发的网络化经纱张力H∞滤波控制策略。首先,分析碳纤维角联织机的工作原理,对整机进行动力学分析及其建模,基于Kelvin模型对织机整体建立张力动态模型,其次,建立织机张力网络化模型,考虑网络时延,采用Bernoulli分布序列来描述随机丢包并引入事件触发机制,构造了一种时滞相关的Lyapunov-Krasovskii泛函,最后,结合舒化补、Jensen不等式和倒凸组合等方法,以线性矩阵不等式形式建立闭环系统的H∞性能条件和控制器设计方法。仿真结果表明:所提控制器抗干扰能力强,提高了张力的控制精度。Carbon fiber angular fabric can be used as a reinforced structural skeleton of composite materials and widely used in various fields because of its excellent characteristics of light weight,high strength and corrosion resistance.Aiming at the accuracy problem of warp tension control of carbon fiber angular loom,an event-triggered H∞filter control strategy was proposed for networked warp tension.Firstly,the working principle of carbon fiber angular loom was analyzed,the dynamic analysis and modeling of the loom were carried out,and the Kelvin model was used to establish the dynamic tension model of the loom.Secondly,the network tension model of the loom was established,considering the network delay,the Bernoulli distribution sequence was used to describe the random packet loss and the event trigger mechanism was introduced.A delay-dependent Lyapunov-Krasovskii functional was constructed.Finally,combining with shur complement,Jensen inequality and inverted convex combination,the H∞performance condition and controller design method of the closed-loop system were established in the form of linear matrix inequalities.The simulation results show that the proposed controller has strong anti-interference ability and improves the control accuracy of the tension system.
