Methods will be presented for controlling the plunge deflections of an aircraft wing structure. One possible solution to improving the flight envelope is a wing design with multiple segmented control surfaces all along its span. This will give an aircraft far more control over its lift distribution in comparison to a typical wing. In order to construct a wing with segmented trailing edges, it must first be shown that deflections under lift loads can be controlled. This paper introduces the research performed by the Structures, Propulsion, and Controls Engineering (SPACE) Center using a Fiber-Optic Strain-Sensing (FOSS) system that is currently implemented on the Odyssey UAV. The research will use a set of strain-based Displacement Transfer Functions (DTF) and the FOSS System both of which were developed at the NASA Dryden Flight Research Center (DFRC). Aerodynamic loads are obtained through the use of the software Athena Vortex Lattice (AVL). In addition, structural modeling is carried out with the use of finite element software. The results indicate that the shape of a wing structure can be controlled through the manipulation of segmented control surfaces to re-distribute lifting loads.","PeriodicalId":350383,"journal":{"name":"21st Mediterranean Conference on Control and Automation","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114384509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, during more challenging dives (such as technical dives) these procedures may not be sufficient to ensure almost accident-free operations, for the divers must manoeuvre in complex 3D environments, carry cumbersome equipment, and focus attention on operational details. Technological advancement and research related to diver safety, navigation and monitoring has been identified as crucial for advancing diving activities. This paper reports current state of research performed at UNIZG-FER related to an autonomous overactuated surface platform used for following divers and transmitting GPS signal to the underwater. The implemented guidance and control algorithms are described and simulations obtained on realistic models developed in the ROS environment are provided. Special attention is given to algorithms for diver tracking by using measurements from a USBL. Diver motion estimators are used to improve the performance of the sparse and noisy USBL measurements. The results presented in this paper are a starting point for in-the-field experiments expected to take place in the real-world environment.","PeriodicalId":350383,"journal":{"name":"21st Mediterranean Conference on Control and Automation","volume":"66 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128666723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, the components of the nonlinear plant are approximated by Fuzzy subsystems. Using appropriately defined “indicating functions”, it is shown that the initial dynamical fuzzy system can be converted to a dynamical neuro-fuzzy model, where the “indicating functions” are replaced by High Order Neural Networks (HONNS), trained by sampled system data. Assuming only parametric uncertainty, the parameters to be estimated are the weights of the HONNs and the centers of the output partitions, both arranged in matrices of appropriate dimensions and leading to a bilinear parametric model. Adaptive laws are derived based on this model and using a Lyapunov stability analysis of the error dynamic equations. The a-priori experts information required by the identification scheme is extremely low, limited to the knowledge of the signs of the center of the fuzzy output partitions. Once the system is identified around an operation point, it is regulated to zero adaptively using an appropriate controller that is built according to the neuro-fuzzy model. The weight updating laws guarantee that both the identification error and the system states reach zero exponentially fast, while keeping all signals in the closed loop bounded. Simulation on a well known benchmark illustrates the potency of the method.","PeriodicalId":350383,"journal":{"name":"21st Mediterranean Conference on Control and Automation","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126248198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tracking control for the pointing of such a large complex multiple-input multiple-output (MIMO) system requires a robust controller to maintain the telescope pointing accurately and reliably at it's target. The segmented space telescope testbed at the Structures, Propulsion, And Controls Engineering (SPACE) NASA University Research Center (URC) of Excellence at California State University, Los Angeles, utilizes a segmented primary mirror and a novel motorized laser platform for simulating the testbed's intended target and demonstrating the testbed's pointing accuracy. The motorized platform along with two sets of accessory mirrors comprises a Peripheral Pointing Architecture (PPA). In order to design a suitable controller, the highly nonlinear geometric model describing the laser paths from source to optical detector plane was linearized to produce an LTI state-space model for controller design.","PeriodicalId":350383,"journal":{"name":"21st Mediterranean Conference on Control and Automation","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126232654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
