A stability criterion for high-frequency oscillations [PDF]
, 2015 We show that a simple Levi compatibility condition determines stability of WKB solutions to semilinear hyperbolic initial-value problems issued from highly-oscillating initial data with large amplitudes.

Frequency stability in resonator-stabilized oscillators [PDF]
IEEE Transactions on Circuits and Systems, 1990 A simplified stability analysis of resonator-stabilized oscillators is carried out by using the describing function approach. On this basis a criterion for the evaluation and optimization of the frequency stabilization introduction in an oscillator by a resonating element with a large quality factor is proposed. In particular, a frequency-stabilization

Design consideration for frequency containment reserve provisions by a multi‐terminal HVDC system
IET Generation, Transmission & Distribution, 2023 Frequency control is considered to be an important function of multi‐terminal HVDC (MTDC) systems. Sharing frequency containment reserves (FCRs) among interconnected AC systems using HVDC technology is particularly attractive in the European context ...

Optically levitated rotor at its thermal limit of frequency stability [PDF]
, 2020 Optically levitated rotors are prime candidates for torque sensors whose precision is limited by the fluctuations of the rotation frequency. In this work we investigate an optically levitated rotor at its fundamental thermal limit of frequency stability,

Decentralized Adaptive Under Frequency Load Shedding Scheme Based on Load Information
IEEE Access, 2019 The inertia of the power system changes when the generators in the system are disturbed or tripped. However, in some systems, there is no control center or communication device falling behind.
