Summary: The extended modification phase of the superconducting fusion experiment Wendelstein 7-X (W7-X) was completed in late 2021, including the installation of actively cooled divertor units and the integration or modification of new technical components and diagnostics. The commissioning of the W7-X experiment is currently ongoing, with technical plasma operation scheduled for September 2022 and scientific plasma operation planned for November. The fast interlock system (FIS) plays a crucial role in protecting the inner plasma vessel components from thermal overload. The requirements for the FIS have been substantially modified and extended to address the challenges posed by the actively cooled divertor, leading to extensive revisions in its technical implementation and software.

Summary: In this article, a Fuzzy Controller-enabled Autoencoder Framework (FCAF) is proposed to detect anomalies that may arise due to cyberattacks in the smart factory environment. The model can sense any rapid deviation from normal behavior once the attack commences and also detects unforeseen anomalies. The proposed technique achieves a specificity of 93% and a sensitivity of 49.9%.

Summary: This article studies the security synthesis of cyber-physical systems subject to stealthy attacks using zonotopic set theory. The set is used to measure the impact of potential stealthy attacks on the systems. Control performance and security level are described using L-infinity performance index and the radius of the attack-induced state set. Sufficient design conditions are provided to optimize security while ensuring a specified level of control performance. Simulation examples are conducted to demonstrate the effectiveness of the proposed method.
