Chaotic artificial neural system and its control

This paper discusses control of chaos from an artificial neural cell. The cell is piecewise linear and includes bipolar hysteresis. A periodic stimulation switches the action potential represented by oscillation frequency and causes chaotic response. Using a mapping procedure, we can prove chaos generation and calculate the initial point of unstable periodic orbits (UPO) embedded in chaos. Then we can stabilize the desired UPO by using a modified occasional proportional feedback (OPF) which is applied only if the stale is in a linear region and must stabilize the desired UPO in a theoretical sense. This OPF function is verified by laboratory experiments.
