The H_∞ 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 fault of previous H_∞ algorithm,by constructing a new difference inequality,a new improved H_∞ algorithm is proposed.In the new algorithm,the upper bound of H_∞ norm is not necessarily previously given and the computation of inverse matrix is not needed.Compared with previous algorithm,new algorithm is less conservative.Numerical simulation example shows that the method proposed is valid.
