Slow resonance ratio control for vibration suppression and disturbance rejection in torsional system

IEEE Transactions on Industrial Electronics, 1999
: In the resonance ratio control, which we proposed for vibration suppression and disturbance rejection in torsional system, the estimation speed of the disturbance observer should have been much faster than the resonance frequency of the controlled ...

Shot-noise suppression in resonant tunneling

Physical Review B, 1995
Substantial shot-noise suppression has been observed in a series of asymmetric double-barrier resonant-tunneling diodes. The suppression is only seeen in the voltage range where the peak resonant-tunneling transmission coefficient is near unity and where there is a large charge buildup in the quantum well; in other voltage ranges, full shot noise is ...

Inverter-Current-Feedback Resonance-Suppression Method for LCL-Type DG System to Reduce Resonance-Frequency Offset and Grid-Inductance Effect

IEEE Transactions on Industrial Electronics, 2018
For the LCL-type grid-connected distributed generation system, the grid-current-feedback active damping (GCFAD) methods have a conflict between the resonance-suppression ability and harmonic-currents amplification.

Vibration Suppression of a Principal Parametric Resonance

Journal of Vibration and Control, 2009
In this paper, a control method that combines linear and nonlinear-velocity feedback control is proposed to suppress the principal parametric resonance in a flexible cantilever beam structure. Linear-velocity feedback is employed for bifurcation control, and cubic-velocity feedback is employed to suppress high-amplitude vibration. A unified bifurcation

Suppression of chaos by resonant parametric perturbations

Physical Review A, 1990
Starting from a chaotic regime in the dynamics of a Duffing-Holmes oscillator, we show how it is possible, by means of a small parametric perturbation of suitable frequency, to bring the system to a regular regime. This situation is studied from the analytic point of view using the Melnikov method and from the numerical point of view computing Lyapunov
