The concept defines a dynamical systems mechanism wherein an output signal inhibits the production or intensity of the initiating stimulus, resulting in homeostatic stabilization. This principle formalizes the negative feedback control loop, a fundamental regulatory architecture characterized by set-points, error signals, and corrective gains within closed-loop systems. It serves as a universal theoretical construct applicable to cybernetics, control engineering, ecology, and physiology, representing the primary method for maintaining system equilibrium against internal perturbations and external noise.
