Abstract: The controller design problem of a class of non-ideal networked control system with time delay，data packet and wrong-sequence is investigated.For overcoming the conservatism of previous controller design method，by decomposing connected weighting matrix，a new improved algorithm is proposed by using Newton-Leibniz formula.Compared with previous method，new algorithm is less conservative.Numerical simulation example shows that the method proposed in this paper is valid.

摘要： 研究了一类包含网络诱导时滞、数据丢包以及错序等非理想网络模型的控制器设计问题。针对以往控制器设计方法保守性较强的缺点，通过连接权矩阵分解，利用离散形式的牛顿-莱布尼兹变换公式，提出了一种新的控制器设计方法。与以往文献中的方法相比，新方法具有较弱的保守性。数值仿真例子表明，新方法是有效的。
