The active magnetic control system is a promising attitude control option for small satellites. Numerous control algorithms have been developed based on only magnetic torquers or in conjunction with other actuators. In this regard, a comparison study is made for the satellites implementing these two control options. Thus, a general attitude control algorithm for a satellite employing only magnetic torquers (Option A) is established and a new control structure for a satellite employing magnetic torquers and a momentum wheel (Option B) is designed. Both systems are evaluated through numerical treatments. The performance from simulations exhibits that the satellite in option B gives a comparable attitude performance to the satellite in option A. The new attitude control structure for the satellite in option B is a potential control option in small satellites. Although this research is for LEO small satellites in a nominal attitude control operation, but it provides us the trade-offs when designing the magnetic attitude control subsystem for low-cost space missions.
