The book shows the practical application of the conceptual provisions of synergetic control theory to solve the design problems of a new class of controlled electromechanical systems. The characteristic features of modern electromechanical systems (EMS) and the trends of their development. are considered. New applied methods of synergetic synthesis of vector regulators for nonlinear DC and AC EMS. are proposed A separate chapter is devoted to the complex problem of coordinating the management of multidimensional and multi-connected nonlinear EMS. The use of the most adequate nonlinear mathematical models, the variety of problems and control objects, the variability of methods for solving these problems are characteristic features of the presented material. Designed for a wide range of readers - students, graduate students and scientists interested in fundamental management problems, as well as developers and designers of promising EMS.
