Abstract
In this paper we consider design to minimize the difference between the maximum and minimum values of a signal. The term fluctuation is used to denote a half of this quantity. The problem investigated is the extent to which, in response to a step, error signal fluctuation reduction is possible in a SISO discrete-time feedback scheme. Using duality, we derive some results on the influence of plant pole/zero locations on achievable fluctuation reduction, and briefly consider the structure of controllers that have the property of reducing fluctuation close to the performance limit.
