Comments on'parameterization of stabilizing compensators by using reduced-order observers"
In this note, a counterexample of the above mentioned paper(1) 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.
