The proposed fault tolerant inverter is based on four leg where the fourth leg is used to replace the faulty leg. In this study, we propose a new topology of DFIG connected to the DC-bus through uncontrolled rectifier in stator side. In order to control of the output system, A Field Oriented Control (FOC) scheme is adopted in this study. The open-switch fault is studied and a fault detection scheme is proposed. The proposed fault scheme is carried out by analyzing the rotor currents within healthy and faulty operation conditions. Simulation results are presented in this paper to validate the proposed fault tolerant inverter.","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123727769","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 developed controller is based on a parameterized NMPC, a fast gradient solver and a proportional derived controller (PD). The main motivation behind the proposed approach is to improve the tracking performance of fast parallel manipulators and reduce the computation time per control iteration. This control scheme is faster, in terms of computing time, than the classical NMPC and ensures the robustness of the resulting closed-loop system. To demonstrate the effectiveness of the proposed controller, real-time experiments are performed on a 4-DOF parallel kinematic manipulator called VELOCE.","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125811921","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 uncertainty has arisen due to the fact that for a certain class of LTI systems the UDFMs can be moved by discrete-time controllers while they cannot be moved for others. We identify the reason behind this anomaly and provide the conditions for moving UDFMs in LTI systems by sample-data control.

This is particularly the case of Multiple Sclerosis, for monitoring this disease and its treatment. Multiple sclerosis is an autoimmune inflammatory disease of the central nervous system which clinical markers are used today for diagnosis and for therapeutic evaluation. In order to automate a long and hard process for the clinician, we propose a semi-automatic segmentation approach of multi sclerosis lesions in longitudinal MRI sequences. We use firstly a robust algorithm that allows spatiotemporal extraction of these lesions by geodesic active contour model. Then, we recommend an original scheme based on an automated image registration technique for evaluating the evolution of the detected lesions. A quantitative study is presented in this paper to validate our results using the BrainWeb simulator. Very promising results are obtained in the case of clinical data.","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114212501","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}

Accurate modeling of the effect of these processes on the actuator leads to better system reliability estimation. This paper investigates the impact of degradation processes and random shocks on reliability of the actuator over time. Moreover, in industrial automation systems, the actuator becomes more vulnerable to damage. Hence, we propose to model the stochastic degradation process with two laws of degradation (Combined process: continuous wear and accumulated shock damages). However, we will predict the reliability evolution of the actuator. It can be estimated by probabilistic approach, which required to evaluate the pdf of the RUL prediction. Finally, the proposed degradation modeling and remaining useful life prediction are applied to a double-tank level control system. The actuator deterioration process is considered as a source of performance deterioration in physical system.","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123697772","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 use of a large number of cells in the MMC converter has some advantages such as the low switching frequency of the semiconductors, which reduces the switching losses. The MMC also has drawbacks, which are reflected in the complexity of the control of the converter due to the presence of a large number of sub modules (SM). In recent years, many works have established new strategies of the MMC control. This paper presents a review of a Pulse Width Modulation (PWM) method used for the MMC control which is the Phase shifted PWM. Simulations in MATLAB-Simulink are performed to validate the control and power transfer for two different MMC. A comparative study has presented for the harmonic distortion rate of the MMC converter output voltage.","PeriodicalId":133593,"journal":{"name":"2019 International Conference on Signal, Control and Communication (SCC)","volume":"9 40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123726375","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 technique considerably affects the convergence and exploration exploitation trade-off in MsPSO process. Since that, different strategies for determining the value of inertia weight during a course of run have been proposed.
