| Summary: | This paper studies controller design for feedback systems in the
presence of asymmetrically bounded signals, using a case study. An
asymmetric objective functional is used to consider the
asymmetrically bounded signals, which makes possible to derive a
linear programming problem. Solving this LP makes possible to
design controllers that minimize certain outputs, fulfilling at
the same time hard constraints on certain signals. The method is
presented by application to a hydrogen reformer, a system in
petrochemical plants that produces hydrogen from hydrocarbons: a
mixed sensitivity problem is stated and solved, with an additional
constraint given by the asymmetric limitations on the magnitude
and rate of the control signal, and the asymmetricity in the
disturbances. |
