The three legs are placed equilaterally on the base. Base joint rotates about a vertical axis whereas the other two joints rotate parallel to horizontal plane. The main objective of this drive simulator is to reduce the overall cost of a drive simulator which is done by replacing the conventional drive simulators having linear actuators with ones having rotatory actuators. Conventional drive simulators are 6 legged and each actuator is a linear actuator. The proposed design of drive simulator is having 3 legs which leads to increase in workspace and since prismatic actuators are replaced by rotary actuators the overall cost is also reduced.  For the proposed drive simulator, inverse kinematics model is generated in a closed form way and workspace of the fabricated drive simulator is verified and workspace volume is calculated for all possible orientations and plotted. Kinematic control is done through Arduino based on inverse kinematics model.","PeriodicalId":38109,"journal":{"name":"International Journal of Automation and Smart Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42319348","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}

T-S fuzzy model is well known for its efficiency to control complex nonlinear systems. However, for wind generator system, the unknown parts are large and produce disturbances parameters. In order to attenuate, the level of the disturbances parameters observer based is utilized to estimate the unknown parts of the wind system. The control design method is based on Lyapunov function, the generalized gKYP with projection lemma, a PDC (Parallel Distributed Compensation) structure and the finite frequency (FF) technique. The proposed approach is formulated linear matrix inequalities (LMIs) to prove the asymptotic stability in (FF) domain. Finally, an example of wind turbine is show the validity of the proposed new approach.","PeriodicalId":38109,"journal":{"name":"International Journal of Automation and Smart Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47984712","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}

SMEs are too small to have their own R&D. They may be left behind from the digital disruption age. Academic researches that describe the IIoT implementation strategies with Human Computer Interaction (HCI) for SMEs and adoption items of the strategies are rarely known. The paper reveals the IIoT implementation strategies with new HCI for SMEs in multi-dimensional facets. Analyses of IIoT implementation drivers, strategies, capabilities, and benefits on 30 articles from leading publishers such as Elsevier and Springer in the last 7 years are compared. Furthermore, the adoption items of IIoT implementation strategies are developed and quantitatively analyzed from 325 respondents of leading industries in Thailand manufacturing sector based on Technology, Organization, and Environment (TOE) adoption framework. The findings show that the 4 significant adoption items are lightweight flexibility, non-monotonous task of new HCI, top management’s real-time decision making, and market opportunity. These results permit better understanding of how SMEs can learn from the analyzed IIoT implementation strategies with HCI and the analyzed significant adoption items in order to adopt IIoT for their business empowerment, thereby maximizing the IIoT value.","PeriodicalId":38109,"journal":{"name":"International Journal of Automation and Smart Technology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48756700","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}

Although this approach is interesting, it is still unable to detect instantly the change of the continuous state; as a result and in case of a fault, the system can't identify correctly the defected mode.

Several companies are investing huge capital to build wind farms with the aim of obtaining the maximum possible economic return. Therefore, a precise definition of the dynamics of operation of the turbines is necessary in order to appropriately define a system that takes full advantage of the wind energy. In this study, the measurements of the noise emitted by different wind turbines were used to obtain information on the dynamics of operation. A selected range of average spectral levels was extracted in a 1/3 octave band. A model based on the neural network for detection has been developed and applied to identify the operating conditions of wind turbines. The prediction and identification model have returned a high precision that suggests the adoption of this tool for several other applications.","PeriodicalId":38109,"journal":{"name":"International Journal of Automation and Smart Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71154338","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}

In this paper six common defects on wood surface are considered for study. The quality of the wood images is enhanced by Histogram Equalization method. The contrast enhanced images are subject to Thresholding segmentation which examines the objects in the image and identifies the defect. The segmented images are cropped in to small blocks. SFTA feature extraction method is accomplished to extract 21 texture features from the wood images. The extracted features are fed in to the training algorithms such as Levenberg-Marquardt, Scaled Conjugate Gradient, Gradient Descent with Adaptive Learning Rate, Bayesian Regularization and Resilent Backpropagation. The performance of the training algorithms is analyzed with several performance metrics. The result obtained shows a considerable improvement in accuracy of 98.2 % by Bayesian Regularization tool.","PeriodicalId":38109,"journal":{"name":"International Journal of Automation and Smart Technology","volume":"16 3","pages":"107-113"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41307537","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}

Furthermore in second part the PMI observer has been considered for TS fuzzy model to estimate both actuator and sensor faults with introducing a centered noise. Although the k th derivatives of the actuators and sensor faults are not equal to zero and are bounded norm.

This leaves the responsibilities of the permanent central controller to be assumed by the remaining devices in the system, including IoT devices and interface devices such as smartphones and computers. While the capacity for joining devices to a network without the permanent central controller has been considered, device discovery has not. This paper examines existing protocols but finds that while many have worthwhile aspects none are suitable for the task. A novel discovery protocol is proposed, using smartphones or computers as intermittent control devices. This new protocol is developed with the aid of a new Robust Network Development Methodology which is able to anticipate problematic use cases prior to implementation. This methodology was very successfully in identifying and eliminating significant problems with the new protocol. Implementation and measurement of the novel discovery protocol demonstrates the viability and robustness of discovery without a permanent central controller on low cost ESP8266 family devices.","PeriodicalId":38109,"journal":{"name":"International Journal of Automation and Smart Technology","volume":"9 1","pages":"147-158"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43307936","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}

It is established based on synchronized voltages sampling in line terminals using morphology approach. The proposed method uses only pre and during fault voltage phasors while traditional distance protection approaches require current transformers (CT) (with the issue of CT saturation and their errors), knowledge of line parameters and Thevenin impedance calculation. The proposed method is based on the voltage variations in the stationary reference frame (α-β). The changes of enclosed area of the voltage curve in the Clark coordinate due to fault is selected as the location criteria. Results indicates that the method is able to estimate fault point distances.
