Random excitation of a system with bilinear hysteresis [PDF]

, 1960
An analysis is made of the response of a system with bilinear hysteresis to random excitation. It is shown that for moderately large inputs, the additional damping created by the bilinear hysteresis decreases the mean squared deflection compared with ...

Response of a Parametrically Excited System to a Nonstationary Excitation [PDF]

Journal of Vibration and Control, 1993
The response of a single-degree-of-freedom system to a nonstationary excitation is investigated by using the method of multiple scales as well as analog- and digital-computer simulations. The unexcited system has one focus and two saddle points. The system can be used to model rolling of ships in head or follower seas. The method of multiple scales is

Coordination between loss of excitation protection and minimum excitation limit function of voltage regulation system [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2021
Established practice is such that the relay protection system and excitation system are adjusted independently of each other, which very often leads to non-coordinated action.

Research on flexible excitation system applied to improve transient stability characteristics of the receiving-end power grid

Zhejiang dianli, 2022
The transient forced excitation of the traditional excitation system used for synchronous condenser is limited and unmaintainable. A flexible excitation system can improve the crest value of transient forced excitation and maintain the forced excitation ...

Collective excitations in Quantum Dot

, 1999
We investigate different types of collective excitations in a quantum dot containing finite number of electrons at zero magnetic field. To estimate the excitation energies analytically we follow the energy weighted sum-rule approach. We consider the most

Excitation Energy as a Basic Variable to Control Nuclear Disassembly [PDF]

, 1999
Thermodynamical features of Xe system is investigated as functions of temperature and freeze-out density in the frame of lattice gas model. The calculation shows different temperature dependence of physical observables at different freeze-out density. In
