Overview of diagnostic methods for electric pump units of satellite platforms

Abstract

The article gives a brief description of the electric pump unit of the satellite thermal control system as an electromechanical subsystem. General issues of development of diagnostics systems for electromechanical systems are considered. Defects of system parts and the reasons leading to failures of electromechanical units are determined. Using modern sources, an overview of methods and approaches to solving problems of diagnosing defects in the mechanical, electrical, and electromagnetic parts of the systems under study is presented. The advantages and disadvantages of modern approaches are noted. A diagnostic chart of prospective current diagnostics is shown. The paper gives an effectiveness assessment of various methods and practical recommendations for the use of the presented methods for the diagnostics system design for electric pump units of satellite systems. Promising areas of research in the field of diagnostics of electromechanical systems, such as the use of current methods or methods based on neural networks, have been identified.
