As the 3D printing is relatively new technology, it is still far from perfection and there are many static or dynamically changing factors which can affect the quality of the final 3D prints. Considering the relatively long time necessary for printing, it may be reasonable to interrupt the printing process in order to save the filament (or another material) and time in the case of decreased quality of already printed fragment of an object. Such monitoring requires the use of the video feedback with appropriate image analysis methods which should allow a reliable quality assessment of the printed object's part. Typically such assessment should not be based on the comparison with a reference image, as in many image quality assessment methods, because such an image is usually unavailable. Therefore in this paper an approach for the no-reference quality assessment of the 3D prints based on the analysis of the Gray-Level Co-occurrence Matrix (GLCM) and chosen Haralick features is proposed and investigated. Obtained experimental results demonstrate the validity and usefulness of the proposed approach.","PeriodicalId":412057,"journal":{"name":"2016 21st International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133142930","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 primary loop in MFC structure contains so-called “associated model”. This model is controlled by algorithm which makes that process of generation of consecutive amplitudes of model reference response is governed by timevariable time-scale depending on error signal. The algorithm “disconnects” state variable scheme of “associated model” when difference between reference signal and model output is equal to zero. The transient state observed on model output can be easily modified by choice of gains influencing the rate of changes of model state variables. This algorithm yields perfect performance of model output process (lack of overshoots, stability). Using accessible signals representing model state variables, their derivatives as well as error signal one can generate input signal of real plant. For accurate model of plant the plant output signal perfectly follows the model output. The identification inaccuracies can be compensated by controller in secondary feedback loop, like in classic MFC structures. It has been shown that control process can be immediately evaluated with use of IAE criterion by reading of two co-ordinates of model reference response. The attached examples confirm impressive properties of control algorithm synthesized according to proposed methodology.","PeriodicalId":412057,"journal":{"name":"2016 21st International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134148738","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}

There is a need for an efficient, optimal and reliable control of the combined infrastructure. The article presents a flexible, configurable microgrid's resources control system, which executes the task of meeting the electricity demand of local households with regard to economic issues. The system developed by the authors varies from the typical solutions available on the market - each user integrates its resources with the microgrid for personal gain. A decentralized control structure using controllers located in each household, built on open code optimizers and low-cost hardware was developed. In order to minimize the chances of a failure, a solution redundant in the aspects of communication and hot standby control devices was developed. A configurable optimization task, which takes into account settlement system between participants, as well as the possible need for withdrawal of the device, e.g. due to damage was defined. A comprehensive verification was done, using simulations for the sample microgrid with different ways of generating and storing.","PeriodicalId":412057,"journal":{"name":"2016 21st International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132283244","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}
