  • Calculation of adaptive dual circuit systems settings

    The method of calculation of tuning coefficients for adaptive control systems implemented with the help of software and hardware systems and installed programmatically at the time of commissioning is proposed. The described algorithm consists of five steps: at the first step, the settings of the selected controller are calculated according to the known transfer function of the control object; at the second step, the method of structural transformations is the equivalent transfer function of the object controlled by the second controller; at the third step on the received equivalent transfer function of the control object settings of the regulator are calculated using a given algorithm; at the fourth step the calibration calculation of the regulator settings on the transfer function of the equivalent object is carried out; at the fifth step the decision on the end of the calculation is made. It is concluded that the presence of a program for calculating the settings greatly facilitates the process of commissioning of software and hardware systems and can significantly improve the quality of adaptive control of large and many tonnage control objects.

  • Structural model of adaptive contours of bioinstrumental information-measuring system

    The article deals with the question of constructing an analytical model in assessing a person's functional state. It is indicated that for complex measurement problems it is advisable to use the principles of constructing measuring systems, formulated in terms of system functions using the fractal-categorical approach; the technique is applicable in the design and analysis of complex medical complexes, and the resulting system function of a complex medical complex is the basis for further analysis within the selected method; The structural-analytical method for constructing complex systems makes it possible, by analyzing the requirements and constraints of the system, to optimize the functions of transferring control actions, to build blocks, parts of the structure on their basis, and to optimize inter-unit communications. The approach described in the article to the process of hematological research makes it possible to analyze the adaptive response of the body's hematopoietic system to external influences of a different nature and intensity.
