Abstract: This paper focuses on the problem of robust H. state feedback controller design for linear delay systems with time-varying uncertainties. Based on the notion of quadratic H∞ performance, it is proved that if there exists a robust H∞ dynamic state feedback controller, then there must exist a robust H∞ static state feedback controller. Sufficient conditions for the existence of robust H∞ static state feedback controllers are given in terms of linear matrix inequalities, and the design method is also presented. The systems in consideration are more general than those considered in the references. Finally, an example is provided to demonstrate the effectiveness of the proposed method.
