Abstract
The Delayed Resonator (DR) is a recent active vibration absorption technique which uses time delayed position feedback generating ideal resonance feature in a passive vibration absorber. This objective can also be achieved using proportional and derivative (PD) control as well as other more sophisticated routines such as LQR, sliding mode control. In this paper, DR technique is compared with PD, a widely adopted control strategy. Actuator dynamics is taken into account in analyzing the system. An analytical comparison is presented which is followed by an experimental validation of the findings using a single-degree-of-freedom primary structure and an absorber with electromagnetic actuator. Both analytical and experimental results show that the DR and PD implementations can be equally effective in suppressing undesired oscillations. The latter, however, requires a velocity observer, which is an additional complexity beyond the DR feedback structure. [S0022-0434(00)02203-6]Keywords
