Abstract

The dynamic response of a carbon fibre reinforced plastic [0/ + 45/ − 450]s active laminated beam covered by piezoelectric layers is considered. A simple collocated displacement control strategy is implemented by letting the active layers work as actuators and sensors and by constructing an analogue control circuit the characteristics of which are given in some detail. The open- and closed-loop steady-state response of the cantilever beam are then experimentally tested in the range of 40–2000 Hz and the effectiveness of the control mechanism is successfully demonstrated.

    Since beam structures are modelled by partial differential equations (PDE) which possess an infinite number of dimensions, it is hard to propose an effective control strategy to stabilize the system with a limited number of sensors and actuators. In order to overcome this difficulty in the conventional approaches, a modal approach is used to obtain a truncated model of the PDE system, where only the main modes of system are used for control design (Denoyer and Kwak, 1996; Gaudenzi et al, 1997, 2000). In the literature, various control methods have been developed based on this procedure.

    Reducing environmental vibration is an important task in the context of serviceability. Although many studies that address vibration control (for example, [207–211]) are available in the literature, the number of studies proposing active control for the purpose of environmental vibration reduction is low. Fig. 3 presents the application motives of active control research in civil engineering.

    One main objective of piezoelectric shape control is to optimize some control parameters and configurations of PZT actuators for morphing shapes so that the actuated shape can match the desired one as closely as possible [18–20], such as morphing structural shapes of real-world aircrafts by mimicking natural flying creatures [21,22]. Design optimization method has been applied to implement shape control of structures associated with smart materials and been investigated by a number of researchers, in which PZT actuators can be either used as structural layers [23], patches [18,19], or stiffener [24]. Recently, we can find that the more systematic structural topology optimization method [25], rather than conventional parametric optimization schemes, has been applied to structural shape control problems.
