For a continuous-time linear system, a measure for evaluating the L2-sensitivity of a closed-loop transfer function with respect to the coefficients of a state-estimate feedback controller is presented by using a pure L2 norm and taking into account 0, ±1 coefficients. A technique is then developed for synthesizing a state-estimate feedback controller in orthonornal ladder filter structure with several 0 coefficients. Finally, through a numerical example it is shown that the state-estimate feedback controller realized in orthonornal ladder filter structure has very low L2-sensitivity.
