Abstract: In this paper, a method of estimating the width of the robust Gershgorin bands with less conservation is proposed. A lemma of robust diagonal dominance with less conservation is given first. Based on this lemma, the estimation method is derived for the transfer function matrix with uncertain parameters. The estimation obtained through this method is less conservative. Finally, an example is presented to illustrate the method. -
