It is known that SAFs generate distortive components caused by a high switching-frequency voltage source inverter (VSI). A LCL output filter is often used to prevent spreading these distorting signals to the grid side. A usually used linear controller in a LCL output filter unavoidably yields a phase shift between the reference and injected currents that severely deteriorates the filtration quality. In this work, inherently robust conventional/classical sliding mode controller (SMC) is used in the shunt active filter for reducing the phase shift effects over the broad bandwidth, while improving robustness to system's perturbations. In order to prevent inherent very high frequency switching of the SMC that can severely hurt the switching elements, two different continuous SMC are studied. In the first solution, a “sign” function used in discontinuous SMC is approximated by a continuous sigmoid function. The second proposed solution uses an artificial increase of input-output relative degree that allows designing SMC in terms of the control derivative, while the actual SMC function becomes continuous due integrating the discontinuous control derivative. The output of the continuous SMC is pulse-width modulated (PWM) in order to provide a fixed given frequency of control switching, required for the VSI safe operation. The efficacy of the considered electric power system driven by the proposed control algorithms was demonstrated via the simulations, carried out by Matlab, Simulink, and Simscap-Sim_Power_System code.","PeriodicalId":127777,"journal":{"name":"2018 15th International Workshop on Variable Structure Systems (VSS)","volume":"30 31","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120822833","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}

Constituted from deformable elastic backbones, Continuum robots are highly nonlinear and complex. Current control approaches tend to overcome this obstacle by adopting assumptions to the robot's structure aiming to develop models that are both accurate and applicable for real time control applications. The drawback of such approaches is that maintaining those modelling assumptions restricts the robots expected performance. Here, we overcome the drawbacks by utilizing a dynamic model based on Cosserat Rod that is free from those assumptions and capable of accommodating the backbone general deformations. This general model has not been been used in robust control design before as its computationally expensive to simulate for real time control applications. In this paper, we solved the expensive computation problem by employing a sophisticated numerical method known as the Generalized– $alpha$ method. For the control part, a robust controller is designed based on sliding mode control. To avoid drastic changes in the actuating tension, control input saturation is considered in the design process. Simulation examples are included to verify the effectiveness of the proposed designed scheme.","PeriodicalId":127777,"journal":{"name":"2018 15th International Workshop on Variable Structure Systems (VSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131250450","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}
