Abstract
The aim of this work is to investigate the effects of different control strategies for an active vibration control system regarding the control performance, power consumption and constraints of the active vibration control system with electrodynamic inertial mass actuators. As a first step, a control system with a single inertial mass actuator mounted on a single degree of freedom has been considered. The analysis is expanded to an active vibration control system applied to a six cells laboratory truss structure. In the simulations the truss structure is modelled using a reduced state space formulation derived from a finite element model. The parameters for the models of the truss structure and the control actuators used in the simulations are derived from experimental characterizations in the laboratory. Numerical and experimental studies are shown. First results show that different control strategies can give different performance for the same power consumption. Moreover, the achievable performances are limited by nonlinear effects as well as stroke limits of the control actuators.
