Abstract
Existing error compensation method of industrial electronic absolute displacement detector only depends on skilled engineers. This paper proposes a new table method in order to automatize error compensation. An waveform changes according to the parallel resistance for each pole were tabularized and four waveforms were superimposed to minimize total phase error. These process was verified using simulink. As a result of applying proposed method to the real sensor, peak to peak error was reduced from <TEX>$3.428^{\circ}$</TEX> to <TEX>$0.879^{\circ}$</TEX>. In this case, compensation resistance is <TEX>$4.7k\Omega$</TEX> in B pole and <TEX>$20k\Omega$</TEX> in C pole. This compensation rate is comparable to skilled engineers, and it takes 0.8 second which is far shorter than 15 minutes when expert does.
