arXiv:2611.13874v1 Announce Type: new Abstract: One of the major sources of inspiration for neuromorphic engineering is the central nervous system, which is orders of magnitude more efficient than classical digital clock-based computers. Neuromorphic control aims at recreating this efficiency in control systems, combined with (formal) stability and performance guarantees. In our previous work [1], we have established formal guarantees for the emulation of static output feedback controllers implemented using integrate-and-fire neurons. In this paper, we investigate the ``efficiency'' of the resulting controllers in terms of sparse spiking activity. By changing the network structure of our original implementation, foregoing the unit gain assumption made in our previous work, we will establish that the chosen architecture of the spiking controller significantly affects its sparsity and discuss the implications of these observations for the efficient implementation of spiking controllers.
