Abstract
A power capping system (10) and method (200) are provided. In one embodiment, a power capping system (10) includes a power controller (16) configured to calculate an error between a predefined maximum desired power and a power feedback signal associated with actual power consumption of a server (12) and to provide a power capping signal that substantially limits the power consumption of the server (12) based on a predetermined gain constant and the error. The system also includes a management interface (18) configured to generate a normalization factor based on the power feedback signal. The normalization factor can be implemented to normalize the error.
