Firstly, the dynamic pinning strategy is used to reconstruct the communication channel for the system that suffers from DoS attacks to prevent the discontinuous transmission information of the communication network from affecting MASs formation. Then, considering that the leader state is not available to each follower under DoS attacks, a fixed-time distributed observer without velocity information is constructed to estimate the tracking error between followers and the leader. Finally, adaptive radial basis function neural network (RBFNN) is used to approximate the unknown ensemble disturbances in the system, and the fixed-time time-varying formation scheme is designed with the constructed observer. The effectiveness of the proposed control algorithm is demonstrated by the numerical simulation.","PeriodicalId":10986,"journal":{"name":"Defence Technology","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exploding foil initiator (EFI) which could produce plasma during electric explosion can serve as a good carrier for studying the EEC. To investigate the enhancement ability and mechanism of EEC in EFI ignition performance, a kind of EFI chips which could realize the EEC effect was designed and fabricated to observe the characteristics of current and voltage, flyer and plasma temperature during Boron Potassium Nitrate (BPN) ignition of the EFI. It was found that the EEC could enhance EFI ignition in terms of energy utilization, ignition contact surface, and high-temperature sustainability of plasma: firstly, the EEC prolonged the late time discharge (LTD) phase of the electric explosion, making the energy of capacitor effectively utilized; secondly, the EEC could create a larger area of ignition contact surface; last of all, the EEC effect enhanced its high-temperature sustainability by sustaining continuous energy input to plasma. It also was found that the ignition voltage of BPN could be reduced by nearly 600 V under the condition of 0.4 μF capacitance. The research has successfully combined EEC with EFI, revealing the behavioral characteristics of EEC and demonstrating its effective enhancement of EFI ignition. It introduces a new approach to improving EFI output, which is conducive to low-energy ignition of EFI, and expected to take the ignition technology of EFI to a new level.","PeriodicalId":10986,"journal":{"name":"Defence Technology","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to lower the firing voltage below 1 kV, an integrated EFIs with enhanced energy efficiency was designed. Corresponding exploding foil initiator chips were fabricated in batch via micro electromechanical systems technology by integrating a unified foil, a flyer layer and a barrel on a glass substrate successively, meanwhile its package of the whole system was proposed at a volume of 2.194 cm. The structural parameters were determined by predicted performance including flyer velocity, impact behavior and conduction property via the proposed theoretical models and the static electric field simulation. As expect, this integrated EFIs exhibited excellent functions, which could accelerate the flyer to a terminal velocity over 4 km/s and preeminently initiate HNS-IV pellet at a circuit of 0.24 μF/0.9 kV. Furthermore, the theoretical design, fabrication and performance test have been all included to validate the feasibility of this integrated EFIs that was beneficial for its commercial development in the future.","PeriodicalId":10986,"journal":{"name":"Defence Technology","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2024-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141784749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
