We considered a non-stationary optimal control system with delay. Non-stationary optimal control systems are described by systems of differential or differential-algebraic equations. Variable coefficients do not allow, in general, to construct a solution to such systems in quadratures. Numerical or asymptotic methods are used to solve such systems. <strong>Design \/ Method \/ Approach<\/strong>. In this paper, asymptotic methods are used, in particular, the Feshchenko-Shkil&#8217; method for integrating singularly perturbed systems and the Wasow\u2019s method for systems with an unstable spectrum. <strong>Findings<\/strong>. In this paper, we construct a transformation that reduces the optimal delay control system to a system that does not contain terms without rejecting the argument. This transformation makes it possible to integrate the system by the method of steps without solving systems of differential equations at each step. <strong>Theoretical Implications<\/strong>. The system of equations obtained as a result of the transformation of the original system is somewhat easier to study in terms of building a solution. However, the problem of optimizing the control of both systems requires both a separate mathematical study and clarification of the practical reality of spectrum instability in such systems. <strong>Practical Implications<\/strong>. If the instability of the spectrum is caused by the degeneracy of the main matrix, this leads to the unboundedness of the system solution as the small parameter approaches zero. The aforementioned growth of the solution can create emergency situations in real systems. <strong>Originality \/ Value<\/strong>. The delayed control systems in the described formulation are studied for the first time. <strong>Research Limitations \/ Future Research<\/strong>. Future research concerns solving the problem of optimal control of systems with an unstable spectrum and studying the question of the reality and physical meaning of turning points in specific systems.<\/p>\n\n\n\n<div style=\"height:18px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-right is-layout-flex wp-container-core-buttons-is-layout-765c4724 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/cims.fti.dp.ua\/j\/article\/view\/256\" target=\"_blank\" rel=\"noreferrer noopener\">ACCESS ARTICLE<\/a><\/div>\n<\/div>\n\n\n\n<div style=\"height:18px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-default\"\/>\n\n\n\n<div style=\"height:1em\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group is-vertical is-content-justification-right is-layout-flex wp-container-core-group-is-layout-b6c475e2 wp-block-group-is-layout-flex\">\n<div class=\"wp-block-group is-content-justification-right is-nowrap is-layout-flex wp-container-core-group-is-layout-fd526d70 wp-block-group-is-layout-flex\"><div class=\"taxonomy-post_tag wp-block-post-terms\"><a href=\"https:\/\/fti.dp.ua\/conf\/tag\/cims-2024-autumnal\/\" rel=\"tag\">CIMS 2024 Autumnal<\/a><\/div>\n\n<div class=\"wp-block-post-date\"><time datetime=\"2024-11-12T13:21:39+02:00\">November 12, 2024<\/time><\/div><\/div>\n\n\n<div class=\"taxonomy-category wp-block-post-terms\"><a href=\"https:\/\/fti.dp.ua\/conf\/session\/electronics-2\/\" rel=\"tag\">Control Systems, Telecommunications and Navigation<\/a><\/div><\/div>\n\n\n\n<div style=\"height:1em\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-default\"\/>\n","protected":false},"excerpt":{"rendered":"<p>Integration of Non-Stationary Optimal Control Systems with Delay and an Unstable Spectrum Petro Samusenko ORCID: https:\/\/orcid.org\/0000-0002-4241-6173 National Technical University of Ukraine \u201cIgor Sikorsky Kyiv Polytechnic Institute\u201d Tetiana Novik ORCID: https:\/\/orcid.org\/0009-0003-3146-6292 National Aviation University Mykola Rashevskyi ORCID: https:\/\/orcid.org\/0000-0003-1136-2691 National Aviation University Purpose.
