Boundary controller design for floating beam structure with unknown system damping in regular wave
2021, Ocean EngineeringCitation Excerpt :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.
A review of active structural control: Challenges for engineering informatics
2011, Computers and StructuresCitation Excerpt :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.
Shape morphing of laminated composite structures with photostrictive actuators via topology optimization
2011, Composite StructuresCitation Excerpt :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.
