The proposed Direct Power Control (DPC) strategy employs a nonlinear sliding mode (SM) approach to directly calculate the required converter's control voltage so as to eliminate the instantaneous errors of active and reactive powers. In this configuration, the extra current control loops are eliminated, which simplifies system design and improves the transient performance. This improved control strategy combines the DPC strategy, sliding mode approach (SM), and switching table (ST) selection vectors technique, so as to directly regulate the instantaneous active and reactive powers of grid-connected voltage source converters. Simulation results for the proposed Variable Switching Frequency Direct Power Control based on Sliding Mode control approach (VSF-SM-DPC). The proposed VSF-SM-DPC is capable of providing enhanced transient performance, and keeps the steady-state harmonic spectra. The robustness of the proposed VSF-ST-DPC to the effect of the line inductance values mismatch is also inspected during active and reactive power changes. The proposed VSF-SM-DPC is inspecting to tracking capability with high-control bandwidth.","PeriodicalId":125957,"journal":{"name":"2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"754 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132867767","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}

This work models and optimizes a new swimming microrobot design for biomedical applications. The key idea behind this contribution is to find out the best dimension and electromechanical parameters of the investigated swimming microrobot that will yield the maximum thrust force for reliable swimming microrobot applications. The analytical models are developed to calculate the thrust force generated by a hybrid tail. The microrobot is modulated using a nonlinear model-based approach for magnetical control. We show that our proposed device can be significantly improved by using the IPCM hybrid tails with thick link at the end of the tail. Furthermore, the artificial bee colony algorithm is used to ameliorate both, electromechanical parameters and the microrobot geometrical aspect, in order to enhance the performance and robustness behavior of the investigated microrobot. In this context, thrust force of the investigated structure is examined and compared with the conventional microrobots. The obtained results demonstrate that the proposed design can be considered as a potential candidate for high performance microrobot-based applications.","PeriodicalId":125957,"journal":{"name":"2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115645654","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}

This research is mainly fuelled by the wide range of potential applications where gait biometrics could be useful as the case of visual smart surveillance and forensic systems. In this research paper, we present a Haar-like template for the temporal markerless extraction of gait features under various camera viewpoints. A markerless model-based method whereby angular model templates describing the human motion are employed to guide the extraction process. Gait features consist of the angular measurements for the lower legs in addition to the spatial displacement of the human body. To further refine gait features based on their discriminatory potency, a feature selection algorithm is applied using a newly proposed validation-criterion based on the proximity of neighbours belonging to the same class. Experimental results revealed that gait angular measurements derived from the joint motions can achieve a correct classification rate of 73.6% after applying a rectification process back into the sagittal plane.","PeriodicalId":125957,"journal":{"name":"2014 15th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114332253","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}
