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.
