Abstract:
      In this paper, we mainly consider weighted sensitivity minimization by a stable controller for linear time-invariant and time-varying systems. The problem is reduced to a distance problem from an operator to the nest algebra. And we give the existence and its computation of an optimal stable controller for the distance problem.
