Sensor fault estimation and isolation is significant for an attitude control systems model of a
satellite, as it works in a complex environment. The standard unscented Kalman filter …

To improve the reliability of the attitude determination system with redundant gyroscopes,
this article proposes a gyroscope fault accommodation method using a bank of dedicated …

This work investigates the actuator fault detection, isolation, and reconstruction (FDIR) for
the spacecraft attitude control system (ACS) under unknown model uncertainty and colored …

This article proposes a fault diagnosis method for closed-loop satellite attitude control
systems based on a fuzzy model and parity equation. The fault in a closed-loop system is …

This paper proposes a novel fault diagnosis and robust fault-tolerant control strategy for over-
actuated systems which subject to actuator faults. Firstly, the considered fault is formulated …

In this paper, a fault diagnosis method is proposed based on component-wise expectation
maximization algorithm and k-means algorithm, and it is applied to diagnosing the fault of …

In this paper, a model-based fault diagnosis method is investigated for gyro. An adaptive
observer is designed to detect the occurrence of gyro fault. And then, the size of fault is …

This paper proposes a fault diagnosis approach for the satellite attitude determination
subsystem based on analytical redundancy and empirical mode decomposition (EMD) …

Due to that some parameters are unable to be measured in orbit, it is difficult to establish a
precise physical model for in-orbit satellite flywheel. Aiming at this issue, a telemetry-data …
