Interpolation techniques used for time alignment of multiple simulation models

摘要

A system for performing time conversions that includes a processor configured to generate a set of target time-series data from a set of source time-series data and a memory containing specification information relating to the set of target time-series data and also containing information relating to the set of source time-series data. The source time-series specification and the target time-series specification include time intervals between data values. The system also includes a time alignment algorithm used by the processor for converting the set of source time-series data to the set of target time-series data. The converting includes calculation of a set of cubic-spline interpolation constants and the cubic-spline constants.
