OPTIMIZATION OF THE SELECTION OF SOFTWARE ELEMENTS
IN CONTROL SYSTEMS WITH SIGNIFICANTLY DIFFERENT-SPEED PROCESSES
Abstract. A comparative analysis of various methods for solving the problem of determining the spectral characteristics
of mathematical models of control systems is carried out, if the dynamics of the object contains processes that differ significantly in speed.
Based on the model experiments carried out, a conclusion was made about the advantages of using the power-law method and the Khilenko method,
when the range of variation of the rates of the calculated variables is unknown or can change significantly when changing the operating modes
of the object (technological process), as well as in the event of critical situations and the need to “work out” them by control system.
Keywords: control systems, decision support systems, mathematical and software-algorithmic support,
determination of spectral characteristics, Le Verrier–Newton method, Khilenko method, power method.
