Abstract

Power flow and net energy transfer are examined for actively controlled, vibration isolation dynamics. Fundamental concepts of active damping systems are studied by examining the average power flow in the controlled and passive actuators subject to harmonic inputs. Expressions for energies delivered and absorbed by the actuators per cycle are derived for one and two degree-of-freedom vibration models. Sensitivity to system parameters on power flow in the passive and active components is examined. This analysis tool can be useful in the design of low-power active and regenerative systems.
