Samkov O. Invariant amplification-conversion systems of hardware for info-communication equipment of self-contained entities

Object of research: the processes of amplification and transformation of the specified control signal by modulation methods. The purpose of research: development of the theory of invariant amplifying and converting systems (ACS) with multiple-modulation, creation on this basis multi-amplifying-converting systems of information and communications equipment, facilities and autonomous control algorithms for them, which ensures high quality output under the influence of a coordinate-parametric perturbations. Research methods: theory of invariance, the theory of bilinear systems, mathematical interpolation of the Lagrange-Sylvester, the unit hyper calculation and quadriplex transformation method developed by the author, z - transformation, the method of successive point maps, adaptive control theory, the theory of fuzzy sets, developed method of synthesis of systems with fuzzy controllers. Theoretical and practical results, and novelty: the further development of the invariance theory is gained; the invariance conditions of the ACS to the influential perturbations are justified; the dynamic features of multifunctional ACS with compensation of position-parametric influential perturbations are investigated; a new generalized dynamic model of multi-invariant ACS is proposed and justified; bilinear method of studying nonlinear systems is developed; provisions on the structural invariance of the ACS with multiple-modulation as a necessary and sufficient conditions are first formulated; the possibility of providing multi-functional ACS and the principle of balancing of nonlinear transmission channels of general indignation at the program level is analytically justified; previously unknown theoretical positions of quadriplex conversion in the format of a hypercomplex calculations for the analysis and mathematical modeling invariant ACS with repeated modulation. Degree of implementation: The experimental samples produced by TOV "AMІKO Komplekt" (Mykolaiv). Sphere of use - engineering, telecommunications.
