  Using the model of a FitzHugh-Nagumo system in the excitable regime we
investigate the influence of time-delayed feedback on noise-induced chimera
states in a network with nonlocal coupling, i.e., coherence resonance chimeras.
It is shown that time-delayed feedback allows for control of the range of
parameter values where these chimera states occur. Moreover, for the feedback
delay close to the intrinsic period of the system we find a novel regime which
we call period-two coherence resonance chimera.
