Optical fibre sensors have been widely used to measure strain and temperature for smart structures applications. Distributed sensors using fibre Bragg gratings have previously been demonstrated. These sensors have many advantages, including high spatial resolution and no dead-zones, allowing a complete spatial image of a measurand to be obtained. Interrogation systems using a tunable narrowband source have been previously demonstrated, but are limited to monotonically varying wavelength profiles. Volanthen et al. (1996) demonstrated a broadband interrogation system for distributed grating sensors, capable of measuring arbitrary strain fields. Low-coherence interferometry selected the location under interrogation and a tunable filter measured the local wavelength. Further to previously published work, two improved systems are presented. The first system uses electronic processing for rapid and accurate wavelength measurement, whereas the second system uses a commercially available optical coherence domain reflectometer (OCDR) as part of the interrogation system. The latest sensing results from both systems are presented. The ultimate performance limits are examined experimentally and compared to the theoretically derived values. Both thermal and strain measurements have been made using single fibre gratings up to 40 cm in length. Multiple grating sensors have also been combined into a single sensing network, producing a sensor system that is both distributed and multiplexed.
The self-diagnosis function is one of main research contents of smart structures. And it is the foundation of other functions realization of smart structures. Aiming at the localization of present structural damage detection methods and the virtue of Least Square Support Vector Machine arithmetic, Least Square Support Vector Machine (LS-SVM) used to detect damages in fiber smart structures was proposed in this paper and was compared with the improved BP neural network. The experimental research results show that this proposed method is feasible and effective for detecting damages in smart structures. Least Square Support Vector Machine provides the more advanced method for realizing the self-diagnosis function in fiber smart structures.
The research on realizing the self-detecting damage function is one of the main research contents of smart structures, and an important issue related to the self-detecting damage function is the method of damage detection. It has been of an important theoretical meaning and a great practical value for applications of smart structures to research on this issue. Due to the structure damage detectionpsilas essence as pattern recognition or nonlinear regression, damagepsilas nondeterministic attribute, and least square support vector machinepsilas (LS-SVM) excessive sensitivity to isolated data points, fuzzy least square support vector machine (FLS-SVM) is proposed to detect damage locations for fiber smart structures by introducing fuzzy memberships to LS-SVM. The testing results show that, FLS-SVM possesses the higher damage locating accuracy, and the bitter dissemination ability than LS-SVM under the same conditions. And FLS-SVM obtains the better noise immunity, and thus strengthens its own robustness.
Smart structures are a multi-sensor architecture, and the problem of multi- sensor optimal placement involves the cost-effective factor. It has been of great practical value and is worth to researching further to optimize sensors' locations and number for smart structures. For piezoelectric smart composite laminated plates, least square wavelet support vector machine (LS-WSVM) with wavelet kernel function is proposed to establish the performance function of damage detection, and then an improved genetic algorithm (GA) is applied to optimize the performance function. To enhance the algorithm speed, LS-WSVM adopted as parallel mode are combined with GA, that is, a parallel genetic algorithm integrated neural network is constructed to realize the optimal sensor placement corresponding to its primal sensor placement based on damage detection. Simulation results show that the optimal placements of different number of sensors are consistent with engineering judgments, and the optimal sensors' number corresponding to its primal sensorspsila number can be determined through the method of parallel genetic algorithm integrated neural network, and the method possesses the advantages of faster speed, etc..
The applications of Fabry-Perot (F-P) fiber-optic white light interference strain sensor are mainly restricted by the cross-sensitivity effects of the cavity length changes, which caused by the changes of the temperature and stress. In this paper, the sensing principles of the white light interference F-P fiber-optic strain sensor, used to measure the smart structure, is briefly introducted, then the methods to eliminate or weaken the temperature sensitivity of is described. The temperature compensation formula and project implementation are presented during the fiber-optic strain measurement. The temperature compensation method mentioned in this paper, can effectively removes the strain measurement error due to the temperature changes.
Vibration control of flexible structures is observed to be a good way to maintain structural integrity as well as to optimize performance for space structures currently. Taking the piezoelectric flexible structure as research object, this paper focuses on the methodology and implementation of a vibration suppression system. An efficient method to simulate and analyze the piezoelectric plate is presented with ANSYS applied, while an iterative learning control (ILC) algorithm is proposed as the control strategy. A finite element model of the flexible plate is constructed by an APDL (ANSYS parameter design language) program. By transient analysis of piezoelectric flexible plate, the models of the control channel and the primary path are obtained. Finally, an ILC based controller, having good cancellation of the vibration of the flexible plate, is developed. The ANSYS experiments suggest that analyzing the piezoelectric flexible plate by ANSYS is a cost-effective method. The SIMULINK results show that the open-loop PID-type learning algorithm is effective for the active vibration control.
The method of damage detection is an important issue related to the self- detecting damage function for smart structures. Based on smart structures' nonlinear, parallel features, and the existed intrinsic flaws of conventional neural networks, research on Support Vector Machine (SVM) used to detect damages for smart structures has become one of main researches recently. Aimed at the key and difficult research problem on SVM - the selection and construction of kernel functions, a mixed kernel function used to Least Square Support Vector Machine (LS-SVM) is constructed through analyzing the existed kernel functions of LS-SVM. Based on damage detection for smart structures, the parameters of LS-SVM with the mixed kernel are optimized by Genetic Algorithms (GA), and the detecting results are compared with that of LS-SVM based on RBF kernel. The result shows that, the accuracy of damage detection based on LS-SVM with mixed kernel is higher than that based on LS-SVM with RBF kernel under the same condition. Compared with LS-SVM with RBF kernel, LS-SVM with mixed kernel possesses the better dissemination ability and stronger learning ability by absorbing the advantages of RBF kernel and polynomial kernel function.
The application of smart structures is one of the most challenging areas to be involved in today. Enabling technologies for smart structures include materials, advanced actuation, sensing techniques, adaptive computer algorithms with the ability to learn and control outputs, and finally methods whereby energy usage can be optimized. In this paper, some technologies are introduced, such as optical design of wave-front sensors for adaptive optical systems, surface control and vibration suppression of a large mm-wave telescope for smart structures.
It has been of great practical value to optimize sensors' locations and number for the self-diagnostic smart structures. Based on damage detection, Least Square Support Vector Machine (LS-SVM) is proposed to establish the performance function of damage detection for the piezoelectric smart structures, and then quantum genetic algorithm (QGA) is applied to optimize the performance function. To enhance the algorithm speed, LS-SVMs adopted as parallel mode are combined with QGA, that is, a parallel QGA integrated LS- SVMs is constructed to realize optimal sensor placement corresponding to its primal sensor placement. For the more sensors' primal placement, the number of sensors can be reduced effectively through the method of parallel QGA integrated LS-SVMs, and thus leads to cost savings. Compared with traditional GA, QGA possesses the better searching ability and the faster convergence speed.
