摘要
研究了事件触发通讯机制下基于模型的网络化控制系统鲁棒H_∞控制问题。通过构造一个依赖于对象和模型采样状态的事件触发传输方案,并考虑网络诱导时延的影响,将闭环系统建模为一个带有区间时变时延的增广系统。利用Lyapunov-Krasovskii泛函方法,以线性矩阵不等式的形式给出了系统的鲁棒H_∞性能判据和控制器的设计方法。最后,通过一个数值仿真例子验证所提方法的有效性。
The robust control for a model-based networked control system under an event-triggered transmission scheme was investigated. By constructing an event-triggered transmission scheme that depended on the sampled states of both plant and model and considering the effect of networked-induced delays,the closed-loop system was modeled as an augmented system with an interval time-varying delay. Using a Lyapunov-Krasovskii functional method,a robust performance criterion and a controller design for the augmented system were given in terms of linear matrix inequalities. Finally,a numerical example was given to show the effectiveness of the proposed method.
