| description | System and methods for accuracy improvement of an LVDT are provided. Aspects include determining a first voltage from the first PGA and a second voltage from the second PGA, wherein the first voltage is determined from a PGA coupled to a first secondary winding, and wherein the second voltage is determined from a second PGA coupled to a second secondary winding, iteratively performing: analyzing the first voltage to determine a gain correction is needed for a first gain for the first PGA, the gain correction comprising change to the first gain, and analyzing the second voltage to determine a gain correction is needed for a second gain for the second PGA, the gain correction comprising change to the second gain, based on determining a gain correction is not needed for the first gain and the second gain, calculating a position based on the first voltage and the second voltage. |
