“…Hybrid methods are the most common type of hardware redundancy and combine the attractive features of active and passive techniques. 154 However, hardware redundancy needs extra equipment, which means extra cost, mass, and space. Most systems, such as satellites, have cost, mass, and size constraints.…”

A review of advanced fault detection and diagnosis (FDD) techniques in attitude control systems (ACSs) of spacecraft is presented. In the first part of the paper, several types of ACS failure scenarios with their practical solutions are presented. Next, the existing approaches to FDD are considered and classified based on different criteria, including applications and design techniques. The literature of this part showed that to enhance ACS operational safety, predictability of failure of an ACS and/or of its components as well as reducing the possibility of failure occurrence is imperative. In addition, fast FDD of various kinds of failures is necessary to guarantee the required reliability of an ACS. The second part of this study highlights challenges involved with different FDD approaches, emphasizing their practical applicability. Current research gaps in FDD techniques such as insensitive residual signal, process monitoring methods, accurate plant model design, easy-to-use software development, FDD tuning process, dealing with noisy sensor measurements, time taken for fault management, the sensitivity of FDD system to faults, and FDD robustness are further elaborated on. Subsequently, the state-of-the-art FDD and its future needs are reflected on. The results of this study could direct spacecraft manufacturers and ACS providers to focus on future needs and improve ground testing for enhanced operational reliability and redundancy.

“…In [9,14], a simple ideal model of the actuator was expressed, and in [15], a conventional electric motor was used based on steady state parameters; therefore, in these works, neither the electrical power nor related mechanical constraints could be considered. Likewise, Baldi et al [16] presented a simple ideal proportional model with unit gain; however, an accurate mathematical model of the electrical motor was not included in this work, either. In contrast, Bialke [17] presented a precise mathematical model of a type A reaction wheel produced by Ithaco Space Systems, Inc.; nonetheless, some parameters and coefficients used in the model remain unknown, and therefore the proposed model has not been practically applied to date.…”

“…Modeling is used for simulating attitude control subsystem and detecting its fault. In [2][3] an ideal proportional model of the wheel with unit gain is described. A common model of the reaction wheel is presented in [4] in which steady-state parameters of electric motor and frictional torque coefficients caused by bearings are described.…”

Reaction Wheel (RW) is the most popular actuator in the Attitude Control System (ACS) of satellites which has a significant role in performing satellite missions. Reaction wheel supplies the torque and the momentum that is required for satellite attitude control. The RW model which is used in the ACS simulations and FDI algorithms should be an accurate model. On the other hand, each physical module has a special role in the reaction wheel modeling. In this regard, based on elements in the internal structure of this actuator, a precise model of RW is presented. Furthermore, the proposed model of RW is more general and can be used in other types of RW. Moreover, in this paper proposed a new model of the reaction wheel for ACS simulation. The proposed model of RW is validated by a RealTime HIL test bed in the form of set point commands and profile command.Keywords-satellite attitude control, modeling reaction wheel, hardware in the loop, brushless electric motor, disturbance torques of bearing, static and dynamic imbalance
