An oscillation suppression strategy for hybrid DC systems based on virtual resistance

Zhejiang dianli
Hybrid DC transmission systems are prone to DC current oscillations as the parameters of constant DC current controller increase， an oscillation suppression strategy based on virtual resistance is proposed.

Spatiotemporal oscillation of an ion beam extracted from a potential-oscillating plasma source

New Journal of Physics, 2019
A radiofrequency oscillation is successfully superimposed on a plasma potential of a filamented source plasma in an ion beam source while maintaining a constant plasma density, in order to investigate effects of oscillating source plasma potential on an ...

Animation of a complex oscillation multiplied by a complex constant

, 2007
This animation requires Adobe flashThis animation shows two phasors rotating in time in the complex plane. One phasor is a representation of an oscillation, and the other one is that oscillation multiplied by a complex constant.

Oscillation of a nonlinear impulsive differential equation system with piecewise constant argument

Advances in Difference Equations, 2018
We deal with a nonlinear impulsive differential equation system with piecewise constant argument. We prove the existence and uniqueness of a solution. Moreover, we obtain sufficient conditions for the oscillation of the solution.

Constants in the oscillation theory of higher order Sturm-Liouville differential equations

Electronic Journal of Differential Equations, 2002
We find the the exact value of a constant in some oscillation criteria for the higher order Sturm-Liouville differential equation $$ (-1)^{n}(t^alpha y^{(n)})^{(n)}=q(t)y . $$ We also study some general aspects in the oscillation theory of this equation.
