This book is written on the basis of many years of personal experience of the authors in the development of complex space-controlled dynamic systems (extra-atmospheric complexes for astrophysical research, aviation and space simulators). The book formulates methodological principles of their design, based on system methodology. The monograph presents a hierarchy of criteria for the effectiveness of the system. At its upper (first) level are the usefulness of the system, the quality of functioning, the organization of the system, evolutionary efficiency, economic efficiency, etc. Among the criteria of the second level, the initial characteristics of the system, importance, relevance, prospects, scope, noise immunity, accuracy, reliability, sensitivity, quality of management, perfection of structure, complexity, feasibility, resources, possibilities of modifications, etc. are considered.  For each criterion, quantitative indicators, characterizing them and methods of measuring them (calculated, experimental or expert assessments) are indicated.  Empirical dependencies between criteria are determined (by methods of factor analysis and mathematical statistics, using procedures for evaluating hypotheses and weighing factors, etc.).  Based on the introduced hierarchy of criteria and selected rational complexes of solved problems, the monograph presents a hierarchy of systems with estimates of its elements, which serves as the basis for long-term planning of the entire complex of developments and design of individual systems.  In the synthesis of these systems, associated with the choice of constructive schemes and control laws, an iterative method is used to optimize the parameters of the system from the minimum condition of the objective function.  The objective function is formed, taking into account both the reactions of the system to the test effects and synchronous measurements of phase coordinates and control actions during normal operation.  Taking into account the high order of system models and the extreme difficulty of determining the influence of technical parameters on the parameters of control actions, especially with operator control, the spectral composition of control actions is determined during normal maintenance.
