Homeostasis occurs in a control system when a quantity remains approximately constant as a parameter, representing an external perturbation, varies over some range. Golubitsky and Stewart (J Math Biol 74(1–2):387–407, 2017) developed a notion of infinitesimal homeostasis for equilibrium systems using singularity theory. Rhythmic physiological systems (breathing, locomotion, feeding) maintain homeostasis through control of large-amplitude limit cycles rather than equilibrium points. Here we take an initial step to study (infinitesimal) homeostasis for limit-cycle systems in terms of theaverageof a quantity taken around the limit cycle. We apply the “infinitesimal shape response curve” (iSRC) introduced by Wang et al. (SIAM J Appl Dyn Syst 82(7):1–43, 2021) to study infinitesimal homeostasis for limit-cycle systems in terms of themeanvalue of a quantity of interest, averaged around the limit cycle. Using the iSRC, which captures the linearizedshapedisplacement of an oscillator upon a static perturbation, we provide a formula for the derivative of the averaged quantity with respect to the control parameter. Our expression allows one to identify homeostasis points for limit cycle systems in the averaging sense. We demonstrate in the Hodgkin–Huxley model and in a metabolic regulatory network model that the iSRC-based method provides an accurate representation of the sensitivity of averaged quantities.
