Designing a Plurality of Frequency Filters Distributed in a Vehicle On-Board Power Supply System

A method for designing frequency filters, includes (a) setting up a simulation model of a power supply system with frequency filters; (b) determining initial set of filter parameters; (c) calculating the model using the filter parameters in time domain; (d) extracting safety-critical trajectories from the calculated model with underlying interference functions; (e) transforming safety-critical trajectories from time domain into frequency domain; (f) determining transfer functions in s-domain by system identification; (g) extracting pairs of residuals and poles based on transfer functions in s-domain; (h) determining energy loss and voltage stability values based on the residuals and poles; (i) varying the filter parameters; (j) repeating (c)-(h) with the filter parameters varied in step (i), until a termination criterion is reached; (k) after which, selecting, from a set of points with energy loss and voltage stability values determined in step (h), a point lying on a pareto-front of the set of points.
