“…In order to also illustrate the applicability of the results to challenging real-life control problems, we consider the problem (see for example, Lovera and Astolfi (2004), Böhm (2011) and the references therein) of attitude control of a low Earth orbit satellite via magnetic actuators. The linearized continuous-time attitude dynamics of the satellite can be described Böhm (2011) by the following time-varying differential equatioṅ…”

“…Attitude control of magnetic actuated satellites was addressed in [22] and [31][32][33][34]. Using magnetorquer coils for control, a torque is generated by the interaction of the geomagnetic field with the magnetorquer current giving rise to a magnetic moment:…”

Abstract:Integration of flight hardware with real-time simulation increases satellite attitude control system (ACS) reliability by providing greater test coverage through end-to-end testing in a realistic test environment. In this paper, a compound hardware and software simulator has been designed for evaluation and testing of the spacecraft ACS, placing emphasis on the real-time hardware-in-loop (RTHIL) architecture. The environment comprises both real-time control and data acquisition applications on a network of ACS hardware, the MATLAB Real-Time Workshop, and a PCI device to join the hardware and software units. Moreover, a graphical 3D simulator has been designed, enabling the designers and researchers to intuitively analyze the quality of spacecraft maneuvers. Finally, an ad hoc attitude-stabilizing control law for magnetic actuated satellites has been proposed and implemented in the proposed environment and the efficiency, correctness, and robustness of this control law have been verified using RTHIL simulation results.

“…As this field is not uniform, due to the rotation of the satellite around the earth, the synthesis models are naturally periodic at the orbital frequency. Even if it has been proved recently in [12] that using solely these actuators stabilization can be achieved for inertial pointing of a spacecraft, the timevarying nature of the problem as well as controllability issues will always lead to closed-loop performance limitations which are not acceptable when operating in mission mode. Therefore, modern spacecraft are usually endowed with magnetorquers and some type of mechanical actuator, such as reaction wheels.…”

“…In the literature, the problem of attitude control by means of magnetorquers has been tackled in the field of non-linear ( [9] - [12]) and linear control ( [13] - [20]). In the latter, among techniques specifically designed for periodic timevarying models, two major trends emerge depending on the kind of tools used: Periodic Riccati equations, see [13], and Linear Matrix Inequalities (LMI).…”

Abstract-Particularly attractive for small satellites, the use of magnetic torquers for attitude control is still a difficult problem. Indeed, the problem is naturally time-varying and suffers from controllability issues. In this paper, a generic model, taking different kinds of pointing and different kinds of actuators into account, is proposed, linearized and then discretized. Recent studies demonstrate how combining magnetorquers and reaction wheels is attractive. Following the same line, latest LMI synthesis techniques for static periodic controller are applied in this paper to the attitude control problem of a spacecraft equipped with both actuation systems. Simulation results are provided, showing the performance of the obtained control law.
