- Abstract
An algorithm is developed for synchronizing the results of measurements of the emf of the inductor and the position of the coil of the electromechanical system during implementation of the dynamic mode of the Kibble balance. This algorithm makes it possible to scale series of data to a common time scale without using hardware synchronization of the data acquisition devices. The algorithm is based on numerical differentiation of the measurement results using Savitsky–Golay filtering, the selection and minimization by the gradient descent method of a special target function in the form of a standard deviation between temporal values of the emf of the coil and the corresponding values of the speed of the coil motion transformed by differentiation and subsequent interpolation. The proposed algorithm for processing the measurements of the position and emf of the coil has been tested experimentally as part of the Balance research project. The measurement data are obtained by means of measurement with asynchronous interfaces contained in a Kibble balance model. Use of the algorithm has made it possible to reduce the error in processing the experimental data owing to the lack of synchronization of the measured position and emf of the coil by a factor of more than 10 in the dynamic mode of operation of this model of the Kibble balance.
