Several crucial phases of the overall approach to development and design of smart structures are outlined in this paper. They are focused on control of lightweight mechanical structures with respect to active vibration and noise attenuation using piezoelectric actuators and sensors. The research experience and growing interest in development of smart structures have motivated introduction of co...

In this Keynote Lecture, first a novel wavelet-hybrid feedback least mean square (LMS) algorithm is presented for robust control of civil structures through adroit integration of a feedback control algorithm such as the LQR or LQG algorithm, the filtered-x LMS algorithm, and wavelets. Next, a new hybrid control system is presented through judicious integration of a passive supplementary damping...

Smart Structures is a rapidly advancing field with the range of support and enabling technologies having made significant advances, notably optics and electronics. Whilst piezoelectric actuators and fiber optic sensors have been accorded the most attention, other techniques such as Shape Memory Alloys, Magneto Restrictive Materials and Electro-Rheological Fluids also have niche applications. Fu...

We propose a novel application of sBs in embedded optical fibers as a building block for the implementation of optical neural net based on smart structures. By employing well established technology in fiber embedding in structures, and exploiting the ability of sBs as a highly versatile ambient sensor, and its nonlinear optical property of energy addition and subtraction to perform optical arit...

This paper proposes a fuzzy model for predicting nonlinear behaviour of smart structures. The parameters of the fuzzy model are trained using the backpropagation neural network and least squares algorithms. To demonstrate the effectiveness of the proposed Takagi-Sugeno (TS) fuzzy model, a structure equipped with magnetorheological (MR) dampers is constructed and investigated. Various levels of ...

Abstract. The smart sensor technology has opened new horizons for assessing and monitoring structural health of civil infrastructure. Smart sensor’s unique features such as onboard computation, wireless communication, and cost effectiveness can enable a dense network of sensors that is essential for accurate assessment of structural health in large-scale civil structures. While most research ef...

We aim to present mathematical models of smart materials and smart structures. Smart materials are materials which present significant multiphysical couplings. They are integrated in smart structures which take technological advantages of some multiphysical effects. We establish a classification of piezoelectric crystalline materials and propose simplified but accurate models of thin plates or ...
