Oscillations about an Equilibrium Position01:04

Oscillations about an Equilibrium Position

6.6K
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

Damped Oscillations

6.7K
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

Forced Oscillations

7.5K
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

Oscillations In An LC Circuit

3.0K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

RLC Circuit as a Damped Oscillator

2.0K
An RLC circuit combines a resistor, inductor, and capacitor, connected in a series or parallel combination.
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...

BIBO stability of continuous and discrete -time systems01:24

BIBO stability of continuous and discrete -time systems

863
System stability is a fundamental concept in signal processing, often assessed using convolution. For a system to be considered bounded-input bounded-output (BIBO) stable, any bounded input signal must produce a bounded output signal. A bounded input signal is one where the modulus does not exceed a certain constant at any point in time.
To determine the BIBO stability, the convolution integral is utilized when a bounded continuous-time input is applied to a Linear Time-Invariant (LTI) system....

Area of Science:

  • Complex Systems
  • Theoretical Biology
  • Nonlinear Dynamics

Background:

  • Biological systems require flexibility to adapt to unpredictable environmental changes.
  • Autonomy, or self-governance, is a key factor in understanding this adaptive flexibility.
  • Synchronization in populations of oscillators is a fundamental phenomenon in biological systems.

Purpose of the Study:

  • To propose a novel parameter-tuning algorithm for achieving autonomous synchronization in oscillator populations.
  • To investigate the emergence of synchronization through autonomous changes in intrinsic parameters.
  • To demonstrate the system's self-recovery capability of synchronized states after sudden disruptions.

Main Methods:

  • Development of a parameter-tuning algorithm based on a selection principle.
  • Implementation of autonomous changes in intrinsic parameters to drive synchronization.
  • Proposal of a continuous model using the replicator model for selection dynamics.
  • Parameter value determination based on the density profile of oscillators in parameter space.

Main Results:

  • The proposed algorithm successfully enables the emergence of synchronization between populations of oscillators.
  • Populations exhibit robust self-recovery of the synchronized state following sudden breaks in synchronization.
  • The system autonomously selects appropriate intrinsic parameter values to restore synchronization.

Conclusions:

  • Autonomous parameter tuning is a viable mechanism for achieving and maintaining synchronization in biological systems.
  • The proposed selection-based algorithm provides a framework for understanding self-organization and resilience.
  • This approach offers insights into how biological systems maintain functional states despite environmental perturbations.
