Abstract
A method and system for detecting acceleration and force data associated with a rotating device or rotating system is disclosed, which includes a sine table and a cosine table that may be created based on a particular number of measured data points per revolution of the rotating device or rotating system. Data contained within the sine and cosine tables are then dynamically correlated to obtain acceleration and force data associated with the rotating device or rotating system, wherein dynamically correlated data are thereby utilized to determine a required correction necessary to place the rotating device or rotating system in a balanced state. An error calculated based on a sample size and the number of samples obtained since a last index pulse can be utilized to compute the validity of the data. An index may be associated with the sine table and an additional index associated with the cosine table, wherein each of the indexes is formulated based on an angle per index based on the particular number of measured data points divided by 360 degrees. At least one sine element and at least one cosine element may be respectively calculated for the index associated with the sine table and…
