英文摘要：

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.
