    Characteristic express checking of admittance measurement units for cyber-physical systems
    (Publishing House of Lviv Polytechnic National University, 2016) Yatsuk, Vasyl; Pokhodylo, Yevhen; Bubela, Tetiana; Yatsuk, Yurii; Lviv Polytechnic National University
    Measurement of RLC-parameters of objects non-electric nature (for example, biological, agricultural, environmental, etc.) with high metrological characteristics is an essential element for building a cyber-physical systems analytical purposes. The reliability of the measurement results of the equipment can be provided only by periodic metrological control over the exploitation conditions. Traditionally analytical RLC-meters are calibrated by means of standard samples and it leads to significant problems in their metrological assurance and complicates whole procedure. It is suggested to make operating check of admittance measurement units metrological characteristics by use of intelligent devices based on code-controlled measures. Critical analysis of available approaches for measures creation was carried out and an admittance codecontrolled measure scheme based on active simulators was designed. The mathematic model for measuring transfer function, analytical devices calibration process and advantages of the operating check based code-controlled measure was presented too.

    Remote errors correction of multi-channel cyber-physical measuring systems
    (Publishing House of Lviv Polytechnic National University, 2016) Yatsuk, Vasyl; Mykyjchuk, Mykola
    The method of remote auto calibration measurement channels cyber-physical systems in real time using code-controlled measures is described. Additive error components as measurement as well the reference channels is adjusted by switching invert method. It is shown that the resulting measurement error virtually determined by codecontrolled measures error that could it serve as a basis for implementing remote auto calibration and operative check of metrological characteristics of measuring channels cyber-physical systems. The results of the experimental study model code-controlled measures showed good coincidence with the theoretical model.
