THE RESTRICTIONS ACCOUNTING OF OUTPUT DEVIATIONS RANGE ON THE TEST SIGNALS CHOICE DURING THE IDENTIFICATION OF SYSTEMS CHARACTERISTICS3

Abstract: The active identification methods for temporal characteristics of the object in a closed-loop control system are considered in here. A comparative analysis of the binary signals pseudo-random and regular sequence of rectangular pulses is investigated under restricting on output deviation range of the controlled parameter. On the accounting base it is shown that the best signals choice depends on several factors and first of all on the noise level; if relative noise level is not high the regular binary sequence will prefer.

Keywords: identification, test signals, pseudo-random binary sequence, regular binary sequence of rectangular pulses, correlation analyzing, the deviations range of output, temporal characteristics.

NOISE PROPERTIES OF BOLOMETERS BASED ON BISMUTH HIGH TEMPERATURE SUPERCONDUCTOR 10

Abstract: We analyzed sensitivity of the bolometric receivers of IR radiation based on the high temperature superconductor of the Bi-2223 system. Test samples of the HTS structure have been manufactured and their electrophysical properties have been measured. On the basis of experimental data, there has been calculated the noise equivalent power for various designs and working modes of the receiver.

Keywords: superconducting bolometer, noise properties.

VACUUM SENSORS WITH NANOSTRUCTURES BASED ON SIO2-SNO2 AND SIO2-SNO2-IN2O3 20

Abstract: A device and principle of operation of vacuum sensors based on nanostructured SiO2-SnO2 and SiO2-SnO2-In2O3 are described. It was established experimentally that the sensitivity of the vacuum sensors depends on the quantitative composition of the nanostructures. The mass fraction of tin dioxide indirectly (by changing the total porosity) affect the relative change in resistance of the sensing element of vacuum sensors is shown. The using of ternary-component nanostructures based on SiO2-SnO2-MexOy instead two-component nanostructures based on SiO2-SnO2 allows greater control over the sensitivity of vacuum sensors based on nanomaterials is shown.

Keywords: vacuum sensors, nanostructures, sol-gel technology, desorption of gases, porous oxide materials.
