The article describes the results of forecasting models generation of quality and reliability indicators of the electronic means. In the learning process variants of normalizing and centering of controlled parameters are described. Much attention is given to the methods of the Theory of Pattern Recognition and extrapolation methods. This paper gives information about the advanced technique of the models generation and individual forecasting of electronic means for the space equipment. The verification of derived models is investigated in detail. Special emphasis is paid to the analysis of the models efficiency.
The process of interaction of a flare discharge with a resistive film is described. The thermal balance equation is considered. Taking into account the exponential dependence of electrical conductivity on temperature a mathematical model of the interaction of a flare discharge with a resistive film is constructed based on this equation. Increasing the mathematical model accuracy for this interaction is considered.
The article discusses the methodology for developing a predictive model (forecasting operator) of the quality of onboard equipment using the extrapolation method. It is shown that the most efficient information about the quality and reliability of the equipment can be obtained from the results of autonomous tests. The choice of the test object was made. A microprocessor temperature controller was chosen as the object of autonomous tests. The transition resistance between the electrical circuits of the microprocessor temperature controller was chosen as a predicted parameter. The results of the training experiment are presented. To construct the forecasting operator, quasi-deterministic models of linear, logarithmic, exponential, and parabolic forms are used. When developing the models, the normalization of predicted parameter by mathematical expectation was used. The choice of predictive models was based on the criteria of minimum average variance, calculated at the test time points, and the minimum values of the probability of erroneous decisions and consumer risk. The research of the developed operator was carried out, probabilistic characteristics of its efficiency are obtained.
The article discusses a device for removing the phase response of amplifiers. Describes the principles of its operation are given diagrams voltage outputs blocks that make up the device. The processes of change in the phase shift of the output voltage of the amplifier, signal conversion, and coordinates. Formation of orthogonal initial tension and their conversion from rectangular coordinate system in the polar is probed.The advantage of the device is represented by a high precision removal phase response of the amplifier.
