S. Matunaga et al., VIBRATION SUPPRESSION USING ACCELERATION FEEDBACK-CONTROL WITH MULTIPLE PROOF-MASS ACTUATORS, AIAA journal, 35(5), 1997, pp. 856-862
The use of direct acceleration feedback control for vibration suppress
ion of low-frequency multi-degree-of-freedom flexible structures using
multiple proof-mass actuators is investigated. Considering the effect
of actuator dynamics, closed-loop eigenvalue analysis is conducted, s
ind a simple matrix inequality is obtained for the stability condition
of the closed-loop system, Methods for calculation of the stability c
ondition are suggested. A procedure for actuator parameter optimizatio
n is proposed to assure the closed-loop system performance, Using both
a lumped-mass space structure model and a frame structure model, nume
rical analysis and simulations are performed, and several aspects rela
ting to control design are discussed. The results indicate the effecti
veness of acceleration feedback control for low-frequency vibration su
ppression using proof-mass actuators.
