Query: Schur Method for Robust Pole Assignment of Descriptor Systems via
  Proportional Plus Derivative State Feedback   The pole assignment problem for descriptor systems is a classical inverse
algebraic eigenvalue problem, which has attracted attention for decades. In
this paper, we propose a direct method to solve the problem with the
application of the proportional plus derivative state feedback, intending to
obtain a robust closed-loop system. Theorems on the feasibility of our method
will be presented. Numerical examples show that our method yields poles of high
relative accuracy.
