Abstract: Fault detection and isolation (FDI) techniques are properties of critical importance for any aerospace missions where autonomy and fault identification (malfunction diagnosis) must be present all the time. Current work provides an extended presentation of the Euresis-filter, a multiple model-based FDI technique suitable for small satellites' thruster faults. The main scope of the proposed multiple model-based FDI function is to maintain the spacecraft (S/C) operational and safe (healthy status) as required by the mission, including the analysis, development and design of the Euresis-filter to the LPF model and Monte Carlo simulation results related to thruster faults. Results reveal that the Euresis-filter can serve as an advanced FDI and fault tolerance control (FTC) technique in terms of reliability, safety and mission success when compared to classical FDI/FDIR approaches.
