Application of the Method of Sensitivity Envelope for Studying One Class of Non-Searching Self-Adjusting Systems

The paper is concerned with multi-dimensional nonsearching self-adjusting systems (SAS) with monitoring of frequency responses in the presence of narrow hand and polyharmonic test signals. The study of these system is shown to simplify significantly when sensitivity functions are used which in the case of systems with a harmonic test signal act as an enveloping function and in the case of systems with a narrow band random test signal, as the sensitivity envelope mean. Methods for obtaining sensitivity models in the presence of harmonics of test signals for a rather general SAS flowchart are discussed.
