Fault detection and diagnosis for satellite's attitude control system (ACS) using an interactive multiple model (IMM) approach

The main objective of this paper is development of a fault diagnosis, isolation and detection technique that is constructed based on the interacting multiple model (IMM) algorithm for partial (soft) or total (hard) reaction wheel failures in the spacecraft attitude control system (ACS).

Description
Summary:The main objective of this paper is development of a fault diagnosis, isolation and detection technique that is constructed based on the interacting multiple model (IMM) algorithm for partial (soft) or total (hard) reaction wheel failures in the spacecraft attitude control system (ACS). Based on different scenarios and assumptions, we develop healthy models of the ACS under various operating conditions and construct faulty modes with respect to temperature changes, power supply line voltage changes, torque variations, and unexpected current variations in each motor axis windings of the reaction wheels. Once a fault mode is detected and isolated, we are capable to develop in certain conditions the recovery procedure through feedback control strategies for the ACS
