An improved linear matrix inequality (LMI) representation of delay-independent H-2 performance analysis is introduced for linear delay systems with delays of any size. Based on this representation we propose a new H-2 memoryless state feedback design. By introducing a new matrix variable, the new LMI formulation enables us to parameterize memoryles s controllers without involving the Lyapunov variables in the formulations. By using a parameter-dependent Lyapunov function, this new representation proposed here provides us the results with less conservatism.
