摘要：

The paper will first introduce TARANIS and its mission objectives. Then, after a brief description of the AOCS design, it will focus on the flexible mode issues. Indeed with 4 masts, one arm and a rotating solar array, the AOCS control has to deal with a lot of flexible modes. The most constraining phase is the orbit control phase when the AOCS subsystem uses 4 IN hydrazine thrusters both to modify the satellite orbit and to control its attitude by off-modulation. A specific study has been performed to specify the flexible mode characteristics (forbidden frequencies, damping factor) and to identify the risk to excite them with the thrusters commands. This study has been performed first with a theoretical control stability approach and then with a dedicated simulator of the complete AOCS control loop.
