Abstract: A decentralized robust control problem for a class of discrete vehicle-string bias systems with structure uncertainties is discussed. Information overlapping structure of systems is expanded by the restriction conditions of inclusion principle; Based on the structure uncertainties of systems, the data transmission delay and data packet dropout of systems, the expanded model is discretized; An approach of designing the [H∞] suboptimal robust state feedback controller is proposed for the systems with perturbation. The approaches are proposed by the Linear Matrix Inequalities（LMIs） method. The numerical simulation tests the validity of the results.

摘要： 研究一类具有结构不确定性的离散车组偏差系统的分散鲁棒控制问题。应用大系统包含原理的约束条件扩展系统的信息重叠结构；兼顾系统的结构不确定性、数据传输时延及丢包，将扩展后的模型离散化；采用求解线性矩阵不等式（LMIs）的方法设计出系统存在外界干扰情况下的[H∞]次优状态反馈分散鲁棒控制器。数例仿真检验了结果的有效性。
