Vibration control of a wing box via reciprocal state space framework

Introduces a design approach based on a new framework called 'reciprocal state space' framework in which the state derivative can be sensed and fed back directly. By using accelerometers and integrators, information of acceleration, velocity and displacement can be obtained and fedback. The proposed methodology using the reciprocal state space framework is useful in structural control because accelerometers are widely used in structural control systems. The proposed methodology is is illustrated by considering the vibration control problem for an aircraft wing, modeled by the finite element method.
