Abstract

Self-powered switching control has been proved to be very effective for vibration damping in case it is not possible to power up a fully active system and/or you have stringent requirements from an added weight point of view. However, the capability of harvesting the required energy for switching as well as the authority of the piezo actuator are greatly influenced by the actual position of the patches along the beam as well as by the circuit parameters. Indeed, varying them both control performance and energy requirement strongly change, making feasible or compromising the possibility to obtain a self-powered control system. Moreover, a difference of system or circuit parameters from ideality can affect the behavior of the damping layout.

In this paper the influence of all these parameters on control behavior are deeply studied. Aim of the paper is to provide a handbook to the choice of circuit parameters depending on the control system requirements.
