“…and D wa33 . The structural panel interface point dynamic mass was obtained from its FE model by applying unit forces and moments at one DoF at a time; it was then validated against test results described in [41]. Here the panel was suspended using elastic cords as to reproduce a free-free boundary condition.…”

“…Unlike optical satellites that have vibration suppression measures, laser communication satellites generally need to study micro-vibration characteristics covering the whole frequency range up to 1000 Hz, causing longer and more complex modelling. Remedia et al [8,9], Zhang [10] and Lellis [11] indicated that finite element method for low frequency and statistical energy analysis for high frequency are needed for micro-vibration analysis below 1000Hz, which is time-consume and inapplicable to the engineering.…”

As the laser gradually replaces the microwave for satellite communication, micro-vibration environment of satellites in orbit become the key factor to keep laser link and communication quality. Due to the limited use of vibration suppression measures, micro-vibration simulation covering the whole frequency range up to 1000 Hz is required for laser communication satellites, which is inevitably more difficult than optical satellites focusing on low-frequency characteristics. This paper proposes an engineering algorithm that can quickly and efficiently simulate the micro-vibration environment of satellites within 1000Hz, and the simulation results are confirmed by experimental data.

“…In the fields of semiconductor and optical industry, the micro-vibration generated by the motor rotation and environment noise may deteriorate production quality even damage the equipment (Remedia et al, 2015). Active vibration control (AVC) is commonly used to suppress the low-frequency vibration as the passive vibration control techniques are ineffective in many applications.…”

As a popular adaptive algorithm for active vibration control (AVC), filtered-x least mean square (FxLMS) algorithm sometimes fails to suppress multiple narrowband disturbance. To control multi-frequency structure vibration, parallel-form FxLMS algorithm can be employed. However, the conventional parallel-form FxLMS does not perform well in the situation of disturbance frequency mismatch and wideband measurement noise. For this issue, the majority of the improvement approaches are based on adaptive frequency estimator. It increased the computational burden of the parallel-form FxLMS algorithm. Therefore, taking the advantage of feedback control, a hybrid adaptive control for AVC is proposed in this paper. And the “posterior” residual error is adopted for better robustness. The convergence analysis of the hybrid AVC algorithm is given. Co-simulations with ADAMS and SIMULINK are implemented to verify the effectiveness in micro-vibration control system. Some comparison experiments are implemented in a micro-vibration AVC experimental system for several typical disturbances. Experimental results confirm the feasibility and effectiveness of the proposed algorithm.
