Abstract

Fast steering mirrors (FSMs) are vital for achieving precise beam alignment, yet mitigating vibrations poses significant challenges in demanding settings like vehicle-mounted systems. To resolve this problem, we propose a combined approach of passive vibration isolation and active control to enhance vibration isolation and control performance. A magnetic adjustable stiffness mechanism (MASM) is incorporated into the FSM, allowing it to be tuned to quasi-zero stiffness (QZS) to achieve QZS vibration isolation. Additionally, the adjustable stiffness FSM is controlled in a closed-loop using backstepping control (BSC). Simulation results demonstrate that this combined passive and active approach improves the vibration isolation and control performance of the FSM.
