Abstract:
The bifurcation delay in a dynamical system with time-dependent parameters is an important phenomenon. In general, dynamical systems with time-varying parameters show dynamic bifurcation. The dynamic bifurcations lead to bifurcation delay or bifurcation postponement, and they are dependent on the frequency of the time-varying parameter. This work presents numerical and analytical explanations of how the time-scaling in the dynamical system influences the dynamic bifurcation and thus the bifurcation delay. We show the results for two different nonlinear dynamical systems, such as an ecological system and a neuron model. We show a generic behavior in the bifurcation delay, that is, the delay follows an asymptotic expression as a function of time-scaling. Possible applications are highlighted.

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
