“…In non-feedback techniques, the phase control in a chaotic system have a decisive role. The phase difference between the main drivers responsible for the appearance of chaos linked to external perturbation is considered the key parameter in the control method [11]. The most important factor of control Method is chaotic system associates an external frequency of modulation with the role of an intrinsic reference clock for a control frequency with an adjustable phase shift.…”

we study how to control the dynamics of excitable systems by using the phase control technique.We study how to control nonlinear semiconductor laser dynamics with optoelectronic feedback using the phase control method. The phase control method uses the phase difference between a small.added frequenc y and the main driving frequency to suppress chaos, which leads to various periodic orbits. The experimental studying for the evaluation of chaos modulation behavior are considered in two conditions, the first condition, when one frequency of the external perturbation is varied, secondly, when two of these perturbations are changed. The chaotic system becomes regular under one frequency or two frequencies, But in two frequencies, phase control showed an excellent ability to maintain regular behavior in chaotic window and reexcite chaotic behavior when destroyed. This dynamics of the laser output are analyzed by time series and bifurcation diagram.

“…Accordingly, the veracity of the chaos phase control strategy has been demonstrated in diferent systems exhibiting bursting phenomena [34,35]. Indeed, this technique was successfully applied to control entanglement in quantum parametric oscillators [36] and to manipulate escaping dynamics in an open system [37]. In spite of the variety of potential applications of phase control strategy and an attention drawn on it in recent years, numerous aspects remain unclear.…”

New complex features of a Pinus family plant subjected to wind load by proposing an analog electronic simulator with an active R C realization that mimics the real-time dynamics of the system was examined in this paper. Findings reveal that the periodic or chaotic dynamics of the system depends on the favored initial conditions. We see the dynamical behavior of the plant showing transition from periodic to chaotic states. This is very beneficial because it allows for the observation that when the value of the wind amplitude ratio changes continuously, the plant behavior may change in a discontinuous way. It also helps to understand the impact of wind on the plant dynamics, in particular, and in forest in general, which is very crucial for understanding several plant communities. We show that plants exhibit multiple forms (periodic/chaotic) of repetitive spiking oscillations reflecting the phenomenon of bursting. For the periodic bursting oscillations, we observe that after each peak of excitation due to the wind load, the plant returns directly to its state of rest, whereas the chaotic bursting oscillations break the energy of the wind into decreasing value packets and its occurrence has the merit of reducing the effects of wind energy on the plant; this action ensures the stability of the plant even in chaotic cases. We also observe that the numerical study based on the isospike technique permits efficient discovery and separation between periodic and chaotic orbits visited during the temporal evolution. We also establish through the chaos phase-control techniques that various chaotic oscillations disappeared after applying the chaos phase control strategy in the system compared to the uncontrolled case. Moreover, the chaos phase-control strategy to the system is introduced to instantly inform how the correct choice of the phase minimizes the effects of the wind and thus eliminates chaotic behavior of the plant by simply driving it towards a variety of periodic orbits.

“…The phase control strategy in chaos has been demonstrated in different systems. [5][6][7][8][9][10][11][12][13][14][15] In this article, we study the phase control of a current modulated quantum dot light-emitting diode (QD-LED). QD-LEDs and organic LEDs (OLEDs) are alternative technologies to the consolidated one of solid-state LEDs.…”

We report phase control in a periodically driven chaotic nanosystem consisting of a quantum dot light-emitting diode. Such a dynamical system is a class C laser, whence the charactering features are intrinsically chaotic. Phase control relies on the addition of small parametric harmonic perturbations with adjustable phase. Phase control is demonstrated by changing both frequency and strength of the controlling perturbations. Our results show that phase control has two crucial effects on a quantum dot light-emitting diode. First, it can enhance the spiking behavior in either regular or chaotic regimes; second, it is able to turn periodic behavior to chaotic behavior with a minimal perturbation when a resonance condition at half of the driving frequency is achieved.
