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

Frequency criteria for exponential stability
IMA Journal of Mathematical Control and Information, 2022 Abstract We discuss some frequency-domain criteria for the exponential stability of nonlinear feedback systems based on Popov’s hyperstability theorem. The main results are new bounds on convergence rates for perturbations of the damped harmonic oscillator, including the Hessian-damped case, when the perturbations satisfy certain ...

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 ...

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.
