... motion of the boom. The control logic is based on two contributions, a feedforward and a feedback one. In this study, a nonlinear flexible multibody model was created to simulate the boom’s dynamic behavior. This model was also used to develop and test the control logic. Finally, the control methodology...

...Tom C. Waite; Qingze Zou; Atul Kelkar In this article, an inversion-based feedforward control approach to achieve broadband active-noise control is investigated. Broadband active-noise control is needed in many areas, from heating, ventilation and air conditioning (HVAC) ducts to aircraft cabins...

... a feedforward control scheme. Theoretical approaches developed for the active control of beams have been shown to be useful as simplified models for the rotor scenario. This paper also introduces the time-domain LMS feedforward control strategy, used widely in the active control of sound and vibration...
