Abstract: Purpose. To generalize the parameters of the original excitation control system for synchronous drives for the dissemination of their results to powerful production complexes operating in periodic shock load modes, which will contribute to the elimination of accidents due to the destruction of the electromagnetic system structure of synchronous machines of mechanisms of this type. Methodology. The research used the provisions of the theory of electrical machines, the theory of automatic control, methods for solving optimization problems using the mathematical package MATHCAD, methods and techniques of structural modelling in the MATLAB environment of the SIMULINK component. Findings. By solving the optimization problem, polynomial dependences of the forcing levels of the excitation system of the synchronous drive were obtained, taking into account the magnitude of the current load and the standard parameters of the elastic coupling, and also the parameters of the PI controller are determined with the refinement of the integral link coefficients, which allows avoiding excessive oscillations in the extreme load rollover process. Originality. Taking into account the technological conditions of operation of the TPA-350 automatic machine tool for the production of solid-drawn pipes, an original sequence was proposed and polynomial dependences of the generalization of the main control parameters of the excitation system of a synchronous drive operating in the mode of periodic occurrence of extreme loads were obtained and the prospect of using this system as part of industrial exciters for powering inductor windings of powerful synchronous drives of metallurgical and crushing and grinding mechanisms is shown. Practical value. The obtained polynomial dependences of the main parameters of the excitation control system forpowerful synchronous drives make it possible to recommend specific forcing values to manufacturers and designers, parameters of the PI controller and the intensity setter, which will avoid expensive repairs and downtime of the machine, which are associated with significant financial costs.
