However, the aliasing error which comes from multiple debris through an inductive debris sensor together is difficult to be avoided. Aiming to this problem, this paper uses a segmented function to describe the behavior of debris aliasing and discusses maximum aliasing error under different debris sizes and spacings. On this basis, an optimized detection strategy is developed to reduce aliasing error. Finally, the simulation based Sine waveform is performed to validate the proposed method. The result indicates the proposed method can switch between the several strategies in different situations that it has the best performance among them.","PeriodicalId":130891,"journal":{"name":"2019 IEEE 15th International Conference on Control and Automation (ICCA)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123904132","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 particular, there is one agent appointed as the pathfinder in the group who is responsible for measuring the relative bearing with respect to an uncertain target. The objective is to drive all the agents such that they first localize the given target and then circumnavigate it with equal spacing. A distributed control algorithm is developed by introducing a distributed observer. In terms of Lyapunov theorem, it is shown that the proposed control algorithm guarantees the achievement of the localization and circumnavigation objective. Experiment results verify the effectiveness of the proposed distributed control algorithm.","PeriodicalId":130891,"journal":{"name":"2019 IEEE 15th International Conference on Control and Automation (ICCA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130071228","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 energy cannot be recovered and increases the temperature inside the underground tunnels requiring further energy for cooling. Consequently, it is beneficial to use energy storage systems (ESSs) to capture the regenerative energy and release it back to the trains when needed. ESSs have been shown in literature to enable energy saving, reduce peak demand, and minimise voltage peaks and troughs. This paper focuses on the high power and high energy requirements of the ESS that exceed the capabilities (within physical and cost constraints) of the state of the art storage technologies such as batteries. In this study it is discussed how batteries can be combined with supercapacitors to create a Hybrid ESS (HESS) that has high energy and high power capability. The limitations of using such a system in this application are discussed and a novel control method is proposed to maximise potential gains. This novel control method is implemented as an electrical model of a DC electric railway that is designed using Matlab. The simulation results indicate that the proposed control methodology can increase the energy efficiency of the DC electric railway while minimising the ESS size, cost, and degradation.","PeriodicalId":130891,"journal":{"name":"2019 IEEE 15th International Conference on Control and Automation (ICCA)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127894896","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 the linear discrete descriptor time delay systems (LDDS), the smoothness and continuity concepts are not fully applicable in the stability investigations. A possible solution is to utilize consistent initial conditions x0 capable of generating the causal solution sequence $(mathrm{x}(k):kgeq 0)$. In this study, a geometric description of such initial conditions is investigated. New delay dependent asymptotic stability conditions were derived. For the simplification of the practical implementation, these conditions were expressed in terms of system matrices $(E, A_{0}, A_{1})$ only. Therefore, complicated algebraic transformations are not required when the stability of such systems is analyzed.","PeriodicalId":130891,"journal":{"name":"2019 IEEE 15th International Conference on Control and Automation (ICCA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116623075","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}
