The Robust Hinfty Controller for a Class Uncertain Linear Systems with Time-delay

The problem of robust H_infin control for a class linear systems with time-delay and parameter uncertainty has been discussed in this paper. The analysis result of robust H_infin control is obtained for this system to be quadratic stabilizability and satisfy the given H_infin norm-bounded via linear immemorial state feedback from interference input to control output. The sufficient conditions for the existence of robust H_infin controllers for uncertain linear systems are given in terms of linear matrix inequalities. The design method of robust H _infin controllers for this system is given
