The purpose of this work is substantiation of new approaches to construction of electric measuring devices for wide application. Opportunities of distribution of the signal transformations in measuring channels of devices which are intended for definition of the complex resistance parameters of any kind are considered. The most part of the transforming are carried out by means base hardware - the software complex which is unified for construction of the broad audience of electric systems. Structures of multi-parametric wide-band measuring circuits with use of the integrated components, providing a necessary set of functional transformations of signals and balancing of the bridge for any equivalent circuit of object of measurement are discussed. Mathematical models and algorithms of measuring process are considered. 2012-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/62219 Определение параметров импульсной последовательности для адаптивного способа измерения вольт-амперных характеристик полупроводниковых приборов Ермоленко, Е.А.; Бондаренко, А.Ф.; Баранов, А.Н. To implement the adaptive pulse method for measuring the current-voltage characteristics of semiconductor devices the mathematical relation between the duration of pauses that follow the measuring pulses and the power and duration of these pulses is obtained. The use of obtained mathematical formula for specifying parameters of pulse sequence allows to reduce the accumulation of heat in the structure of semiconductor device during the process of measuring the current-voltage characteristics, thereby improving measuring accuracy. 2012-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/62218 Этапы алгоритма квазиоптимального регулирования в системе с импульсным преобразователем Войтенко, В.П. Research problem to create a real time quasi-optimal system on the basis of built in microcontrollers is formulated. In the heart of such system lies the identification of a subsystem called ‘the pulse converter – the unknown (including – nonlinear) load’ by the means of an artificial neural network. This subsystem functions under conditions of changing limitations on the impact levels and in the presence of disturbances. The modified algorithm of optimal regulation is suggested. It allows putting the regulation time in its dependence on the size of the initial mismatch without any numerical solving of the transcendental equation and therefore increasing the speed of the system while fulfilling smaller tasks (for example, a task of parameter tracking). 2012-01-01T00:00:00Z
