The task of iris analysis requires precise steps to yield accurate decisions. Considerable studies have shown that the extraction of the most informative features is one of the important keys for resulting in high level of accuracy. Discrete wavelet transform (DWT) and discrete cosine transform (DCT) have been intensively utilized to extract the features of iris images. This paper provides a technique for analyzing the combination of the features extracted by DWT and DCT all at once. The proposed technique is applied on CASIA interval-v4 image database. For the classification task, the extracted features are fed into the multiclass SVM. The accuracy rates yielded by the proposed technique reached 100%. This is quite promised comparing with those results of processing DWT and DCT separately.","PeriodicalId":158545,"journal":{"name":"2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129597143","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, the multiobjective optimization problem is converted to single-objective problem. Particle Swarm Optimization (PSO) algorithm is then used to conceive appropriate control parameters, for the purpose to reduce fuel consumption and emissions with conserved vehicle performance requirements. To simulate a parallel hybrid electric vehicle, ADvanced VehIcle SimulatOR (ADVISOR) is used with Federal Test Procedure (FTP) and Urban Dynamometer Driving Schedule (UDDS) to estimate Fuel Consumption (FC), emissions and vehicle dynamics.","PeriodicalId":158545,"journal":{"name":"2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129265266","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 locomotion of such bipedal robot is modeled by an impulsive hybrid nonlinear system, which can generate surprising phenomena such as chaos and bifurcations, by varying some parameters. In order to make the walk of the compass-type bipedal robot to be periodic of period 1, we propose two control approaches. The first control method is based on tracking a predefined passive dynamic walking generated by the model itself. The second control approach is based on following an online planned trajectory using the 4th-order Spline function. Finally, we show some simulation results revealing the efficiency of the two proposed control approaches in the control of the passive gait of the bipedal compass-type robot.","PeriodicalId":158545,"journal":{"name":"2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206374","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}

Therefore, the reduction of these elements was one of the important studies in electrical power systems. The choice of the Jaya Algorithm (JA) was good for this goal because it is a fast, efficient and stable method that gives a global optimization solution in most cases. Thus, it is a method based on only one simple equation. This method is applied to typical electrical grid 30-node of IEEE in order to reduce the total real losses as well as with voltage deviation and the coefficient of voltage stability. Additionally, the reduction of losses and voltage deviation with the coefficient of voltage stability is treated because the decrease in the voltage deviation leads to an increase in its stability index and vice versa, which makes it a multi-objective optimization problem.","PeriodicalId":158545,"journal":{"name":"2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130398618","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}

According to the New European Driving Cycle (NEDC) applied to mathematical FC-HEV model, simulation results show that on line self-regulated PI controller based on error optimized by PSO is more effective in terms of stabilization in DC link voltage and vehicle speed than off line method.

Firstly, an Adaptive Fuzzy Observer (AFO) is employed to reconstruct state and actuator's faults. The delivered information by this AFO, is used to develop an adaptive Proportional-Integral-Derivative (PID) active fault tolerant controller. The purpose of the designed PID controller is to compensate the incipient actuator fault impacts and to guaranteeing trajectory tracking of the outputs to the reference responses. Stability and trajectory tracking performances of the suggested methodology are examined by the Lyapunov concept. Sufficient conditions are obtained and solved for the design of the controller and the observer gains using Linear Matrices Inequalities (LMIs). After All, a benchmark model is presented to demonstrate the validity and feasibility of the theoretical results.","PeriodicalId":158545,"journal":{"name":"2020 20th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127035224","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}
