A model-based solution for fault diagnosis of thruster faults: application to the rendezvous phase of the mars sample return mission

Abstract

This paper addresses the design of model-based fault diagnosis schemes to detect and isolate faults occurring in the orbiter thrusters of the Mars Sample Return (MSR) mission. The proposed fault diagnosis method is based on a H(0) ¦lter with robust poles assignment to detect quickly any kind of thruster faults and a cross-correlation test to isolate them. Simulation results from the MSR ¤high-¦delity¥ nonlinear simulator provided by Thales Alenia Space demonstrate that the proposed method is able to diagnose thruster faults with a detection and isolation delay less than 1.1 s.

A TSK-Type Recurrent Neuro-Fuzzy Systems for Fault Prognosis

“…The first step in building a prognostics system, as published in the ISO standard, is the identification of the set of failure modes (FM), their influence factors on each other and the detection measures (descriptors) that allow to track the evolution of the degradation. The international standard IEC 60812 [10] has presented a procedure named "Procedure for failure mode and effects analysis (FMECA)", which helps the identification of all the failure modes for a specific system, by the analysis of its subsystem s and components. Also, the FMECA method classifies the FMs using risk priority numbers (RPN) that are calculated with three failure mode parameters: occurrence (Occ), detection (Det) and severity (Sev).…”

Fixed-time rendezvous control of spacecraft with a tumbling target under loss of actuator effectiveness

“…The active FTC approach is to respond to the failure by reconfiguring the remaining (often redundant) system elements based on real-time information from a fault detection and diagnosis (FDD) scheme. Numerous active FTC strategies have been studied for spacecraft missions in the past decades, for instance, the work of Chen et al [30] and Patton et al [31] about the Mars Express mission, the work reported in Fonood et al [32][33] and Henry et al [34] about the Mars Sample Return (MSR) mission, and the work of Henry [35] about the Microscope satellite. In contrast to active FTC approach, neither an FDD scheme nor a controller reconfiguration mechanism is needed in the passive approach.…”

Spacecraft Actuator Diagnosis with Principal Component Analysis: Application to the Rendez-Vous Phase of the Mars Sample Return Mission

“…Thus, autonomous spacecrafts have become a key technology for increasing their survival capability. Various researchers have developed diagnosis systems to detect and isolate faults that can appear in a spacecraft [4][5][6].…”

“…Numerous fault diagnosis systems have been developed to detect and isolate the thrusters' failures. Most of these systems have been based on an analytic method using a mathematical model [6,14].…”
