A method and system for optimizing the digital filter compensation coefficients of a digitally controlled switched mode power supply within a distributed power system is disclosed A power control system comprises at least one point-of-load (POL) regulator having a power conversion circuit adapted to convey power to a load and a digital controller coupled to the power conversion circuit though a feedback loop The digital controller includes a digital filter having a transfer function defined by plural filter coefficients The digital controller periodically stores samples of the feedback measurement The system controller retrieves stored samples from the digital controller via a se.pi.al data bus After ret.pi.eving a pre-determined number of the samples, the system controller calculates optimized filter coefficients for the digital filter and communicates the optimized filter coefficients to the digital controller for use in the digital filter
