However either the characterization of the sensitivity of model to each input or a preliminary knowledge on the uncertainties on parameters can reveal different required precision on each input. Therefore a blind search of the best set of parameters could be unnecessarily costing in terms of computational effort on the determination of non significative digits. To overcome this problem a solution consists in searching the best parameter sets within a predefined discrete space of search that is designed from the significative number of digits. The strategy consists in transforming the continuous problem into a discrete one that falls within combinatorial optimization eventually before ending the search of the best continuous inputs if required. The performance of continuous and discrete PSO are compared by their application to the inverse problem of the purple color of the Lycurgus cup. The structure of this ancient glass is recovered from photograph by using a direct model of color generation. The discussion of results is also an opportunity to convince that the heuristic approaches provide solutions to the inverse problem unlike nested loops, from a pedagogical point of view.","PeriodicalId":161703,"journal":{"name":"2014 International Conference on Control, Decision and Information Technologies (CoDIT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125357490","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 VRPTW is a bi-objective optimization problem where both the number of vehicles and the distance of the travel to use should be minimized. Because it is often difficult to optimize both objectives, we propose an approach that optimizes the distance traveled by a fleet of vehicles. Such a strategy has been already used by several authors in the domain. Herein, an instance of VRPTW is considered as the composition of the Assignment Problem and a series of Traveling Salesman Problems with Time Windows (TSPTW). Both AP and TSPTW are solved by using an ant colony optimization system. Furthermore, in order to enhance the quality of the current solution, a large neighborhood search is introduced. Finally, a preliminary experimental part is presented where the proposed method is evaluated on a set of benchmark instances and its results are compared to the best results obtained by the methods available in the literature. Our preliminary results show that the proposed hybrid method remains competitive and it is able to reach new minimum distances for some tested instances.","PeriodicalId":161703,"journal":{"name":"2014 International Conference on Control, Decision and Information Technologies (CoDIT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121612879","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}

So, all parts of an experimental set up like aluminum links, AC servo motor and its driver, DC motor, strain gauge sensors, high speed digital to analog convertor (DAC) components on an electrical interface board and National Instrument's LABVIEW software package are gathered. In this paper, it is focused on closed loop control of end effector in presence of load with and without PID controller. Decreasing the power consumption in industrial heavy robots requires to reducing the weight of the robot's links. It causes more deflection and vibration in the end effector of robots. Hence eliminating the deflection and vibration of end effector is a substantial goal in robotic and control researches. Here we try to propose ideas for this problem and it works better if all offered theoretical ideas exam on an actual set up that we have prepared. For the first step a PID linear controller has been tested on experimental set up. Eventually it will caused that getting enhancement in some terms of PID will improve some deviations of the direction due to link's vibrations. On the other hand increasing load on the robot end effector is caused to vibration intensification.","PeriodicalId":161703,"journal":{"name":"2014 International Conference on Control, Decision and Information Technologies (CoDIT)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132463532","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}
