FAULT TOLERANCE OF SPACECRAFT ORIENTATION AND STABILIZATION SYSTEM

S. N. Firsov, O. V. Reznikova

Abstract


Formed the structure of the orientation and stabilization system for ensuring its active fault tolerance. Parameterized types of failures of the system functional elements, characterized by changes in the properties of the conversion elements. Received diagnostic functional models for solving problems of detection, search the place and establish a class of failure for system. Developed models and methods of systematic approach to fault tolerance in the direction of the effective use of the signal, parametric and structural redundancies and selection of parrying tools. Performed experimental researches of the sample model of the automatic attitude control and stabilization the properties of active fault-tolerance in emergency modes of operation.

Keywords


stabilization and orientation spacecraft system, fault tolerance, reaction wheel, angular velocity sensor.
