Abstract :
Robust disturbance rejection bounds obtained recently by Zhu et al. are tight with respect to the disturbance set that has a specified L2 norm bound. It is shown that the bounds are also tight with respect to a weighted L2 disturbance set that has a specified bound on its outer product by choosing a special weight matrix in the L2 norm. The matrix can computed by numerical iteration
