Novel Active Tuned Mass Damper Control Method for Space Telescope

A novel active tuned mass damper (ATMD) control strategy was proposed and the application of the ATMD to the vibration attenuation of a space telescope was investigated. This control strategy, which combines proportional control and positive position feedback (PPF), was shown to have good stability. Moreover, the control strategy is independent of the dynamic characteristics of the ATMD. The effectiveness of the presented control strategy was demonstrated in simulations. The simulation results show that the control strategy can achieve the same effect as ideal PPF force control. To verify the vibration attenuation effect of the developed ATMDs applied to the space telescope, an integrated optomechatronics analysis was adopted. The optomechatronics simulation results show that the ATMDs can efficiently attenuate the elastic resonance of the space telescope and improve the image quality of the optical system. In addition, the ATMDs do not reduce the isolation effect of the isolation system at high frequency ranges.
