Abstract
The influence of actuator damage on the performance of closed loop vibration control isnumerically evaluated. Debonding is considered a damage mode and finite elementprocedures are subsequently developed to introduce its effect on system matrices, namelyelastic and electro-elastic stiffness. A simple modelling scheme for multiple debonding isproposed, which can also idealize multiple delamination in the host laminate.Debonding in actuators in general has reduced their load carrying appreciably aswell as vibration control characteristics. Therefore, incorporating such a damagemode in the control design as an uncertainty parameter would help to realize adamage-tolerant active vibration control system. It is interesting to note thatdebonding in actuators has influenced both active damping and active stiffeningeffects.
