Cellular Football (Truncated Icosahedron) Homeostatic Control Model — A Life Steady-State Engineering Framework Based on Five-Axis Proportional Control and Tensegrity Topology

This work proposes a life homeostasis control framework that models living systems as distributed steady-state systems governed by proportional feedback rather than centralized regulation. The model introduces a five-axis proportional control architecture encoded using tri-state logic and shows that a truncated icosahedron (cellular football topology) represents a minimum-complexity tensegrity structure capable of supporting robust, recoverable homeostasis under continuous energy, material, and information flux. The framework is formulated at the level of system geometry and control principles and is independent of specific species, organs, or measurement techniques. Human biological data are discussed only as one possible implementation context and do not define the model’s constants or scope. This work is theoretical and engineering-oriented, intended for research in systems biology, biophysics, control engineering, and topological dynamics. It does not provide medical diagnosis, treatment, or clinical recommendations.
