Paradox of simple limiter control

Phys Rev E Stat Nonlin Soft Matter Phys. 2006 May;73(5 Pt 1):052901. doi: 10.1103/PhysRevE.73.052901. Epub 2006 May 18.

Abstract

Chaos control by simple limiters is an easy-to-implement and effective method of stabilizing irregular fluctuations. Here we show that applying limiter control to a state variable can significantly shift its mean value. In many situations, this is a countereffective as well as unexpected result, when the aim of control is also to restrict the dynamics. We discuss this effect on the basis of a model of population dynamics and conclude that it can have severe implications for the management of pest species and epidemic spread.
