Output Violation Compensation for Systems with Output Constraints
journal contribution
posted on 2007-11-19, 15:36 authored by Matthew C. Turner, Ian PostlethwaiteThe problem of output constraints in linear systems is
considered, and a new methodology which helps the closed loop respect
these limits is described. The new methodology invokes ideas from the
antiwindup literature in order to address the problem from a practical
point of view. This leads to a design procedure very much like that found
in antiwindup design. First, a linear controller ignoring output constraints
is designed. Then, an additional compensation network which ensures
that the output limits are, as far as possible, respected is added. As the
constraints occur at the output, global results can be obtained for both
stable and unstable plants.
