中文摘要 |
研究了具有多时变状态和控制时滞的Lurie控制系统基于线性矩阵不等式(LMI)的绝对稳定性条件.首先,构造了关于Lyapunov泛函中正定矩阵和积分项系数等自由参数的LMI,获得了系统时滞无关绝对稳定条件.进一步引入自由权矩阵来表示牛顿-莱布尼兹公式中各项的相互关系,得到了系统绝对稳定的时滞相关条件.最后,通过一个实例阐述了本文方法的有效性和相比已有结果的优越性. |
英文摘要 |
Based on the linear matrix inequalty (LMI), some absolute stability conditions for Lurie control systems with time_varying delays in both state and control input are derived. First, the delay_independent absolute stability conditions were obtained, which were described by LMI for the free parameters such as the positive definite matrix and the coefficients of the integral terms in the Lyapunov functional. Moreover, new delay_dependent absolute stability criteria were presented, in which some free weighting matrices that express the relationships between the terms in the Leibniz_Newton formula were introduced. Finally, a numerical example was provided to demonstrate the effectiveness of the proposed method. |
