Sharp changes in T cell population kinetics in response to an infection have been revealed by experimental studies. Striking similarities are shown to exist between the phase portrait of a classical VSCS and the phase portrait of an accurate model of the T cell response with an on/off activation function. The robustness properties of the T cell response dynamics described in current experimental and mathematical studies are evaluated using Lyapanov stability theory and numerical simulations. The findings demonstrate that the T cell dynamics following vigorous infection behave as a closed-loop system under variable structure control. This control law effectively determines the immunological control structure and the metabolic energy regime required to ensure that the dynamics of the responding T cells maintain a healthy state. The VSC paradigm thus provides a mechanism to understand the transition from health to disease.","PeriodicalId":297041,"journal":{"name":"2015 International Workshop on Recent Advances in Sliding Modes (RASM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129629008","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}

These micro generation units can be used as standalone applications or grid connected applications. However to get the full potential benefits of these wind turbines, systems should be low cost and reliable. Introducing the wind speed and rotor speed sensors at the generator shaft may reduce the reliability of small wind turbines. In this study, a grid connected sensor-less 5 kW small wind energy conversion system has been studied. The maximum power point tracking method of the wind turbine is totally independent from wind speed and rotor speed measurements. Optimum rotor speed and actual rotor speed are estimated using output current and voltage of the generator. To estimate the optimum rotor speed of the wind turbine, power signal feedback method has been used. Moreover, a sliding-mode observer is designed to estimate the rotor speed. Performance of the sliding-mode observer system has been compared with the measured rotor speed based wind energy conversion system. The simulation results show the effectiveness of the proposed sensor-less control system for the system under consideration.","PeriodicalId":297041,"journal":{"name":"2015 International Workshop on Recent Advances in Sliding Modes (RASM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128298888","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}

Due to the presence of complex phenomena such as large flexibility, model uncertainties, and external disturbances a robust and adaptive control is required to control the motion of the robots. This paper presents the design of an adaptive chattering-free sliding mode control using two adaptation mechanism namely: a fast and performance-based online estimation of uncertainties, which is constructed based on the dynamic behaviour of a sliding function; and an adaptive fuzzy model of the robot, which is constructed using a systematic fuzzy modelling method and from input-output data of the robot through system identification. These two adaptation mechanism can be interpreted as the integration of fast response to immediate feedback information and the response based on the knowledge that has already been built into the fuzzy model of the controller, which is the model-based component of the ACFSMC. The global stability and robustness of the proposed controller are established using Lyapunov's approach and fundamentals of sliding mode theory. Based on the simulations and experimental results, the proposed controller performs remarkably well in comparison to SMC with boundary layer and the high gain proportional-integral-derivative (PID) controllers in terms of the tracking error convergence and robustness against uncertainties.","PeriodicalId":297041,"journal":{"name":"2015 International Workshop on Recent Advances in Sliding Modes (RASM)","volume":"39 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116416687","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}
