In this paper, a data-driven method for controller design with constraints on the positive-realness of closed-loop transfer functions over an arbitrary set of frequencies is proposed. The positive-realness of a closed-loop transfer function is represented ...
In recent years, power systems have evolved in physical and cyber-physical layers. In the physical layer, the changes are motivated by environmental concerns resulting in the integration of new types of generation/demand/storage into the grid. These integr ...
The maximum gain in on-frequency repeaters is limited by the isolation level between their two antennas due to close-loop stability conditions. In this letter, a novel pixel-layer isolator for tunable on-frequency repeaters is presented. The scattered fiel ...

The safe and reliable operation of modern power system imposes the need to describe and estimate the system stability through impedance-admittance measurement and identification. The integration and operation of medium voltage equipment in existing infrast ...
Modern grids are facing a massive integration of power electronics devices, usually associated to instability issues. In order to assess the likelihood and severity of harmonic instability in the high frequency region, this work develops a multi-variable i ...
This paper reports on energy harvesting from an impact by using a piezoelectric MEMS scavenger. Useful electrical power is generated by the impact of the rotating gear on the MEMS piezoelectric transducer. The design of the device structure was based on bo ...
In the ever-growing world of optical telecommunications. Semiconductor Optical Amplifiers (SOAs) are called to play an increasingly important role. Their attractive performances both in the linear and non-linear regime along with their reduced cost and sma ...
