Abstract :
A counterexample of the above mentioned paper (Fujimori, IEEE Trans. Automat. Contr., vol. 38, p. 1435-39, 1993) is given. It is shown that the parameterization of all proper compensators internally stabilizing the plant is incomplete. Modified parameterization of all proper stabilizing compensators is also presented.
