【Abstract】 The problems of robust H~∞ control for linear systems with a constant time delay in the state and subject to parameter uncertainty is discussed. Systems with norm-bounded parameter uncertainty will be considered.A new algorithm involving convex optimization is proposed to design a robust H~∞ state feedback controller guaranteeing a less conservative delay in these systems.Simulation results show that exist a memoryless state feedbacd controller which make the system stabilization,when time-delay τ change between 0 and 0.4350.更多还原
