Power systems are subjected to low frequency disturbances that might cause loss of synchronism and an eventual breakdown of entire system. The oscillations, which are typically in the frequency range of 0.2 to 3.0 Hz, might be excited by the disturbances in the system or, in some cases, might even build up spontaneously. These oscillations limit the power transmission capability of a network an...

Cyber-Physical Systems (CPSs) are becoming more automated and aimed to be as efficient possible by enabling integration between their operations Information Technology (IT) resources. In combination with production automation, these systems need identify assets the correlation them; any potential threats or failures alert relevant user/department suggest appropriate remediation plan. Moreover, ...

We present the design and experimental validation of wideband dual-circularly-polarized (dual-CP) reflect-arrays (RAs) based on dual-functional-layered unit cells with independent control circular polarizations. The proposed dual-CP RA comprise a polarization selective surface (CPSS) top bandwidth-enhanced dual-meandered Pierrot structure that implements selection CP waves reflective half-wave ...

Dear editor, This letter is concerned with the control of cyber-physical systems (CPSs) in presence malicious false data injection (FDI) attacks on actuators. The FDI actuators may result faults or even instability CPSs. To tackle this problem, an unknown input observer (UIO) proposed to estimate system states and attack signals. For aim suppressing impact attacks, a discrete-time sliding mode ...

Metaverses have caused significant changes in the industry and their academic foundation can be traced back to term cyber–physical–social systems (CPSS), which was proposed 2010. Radar is an important sensor sensing that are widely applied many fields, especially, autonomous driving. To deal with complex environment, smart radars real-time information processing capabilities required. Human fac...
