Bifurcation refers to a phenomenon in which a slight change in the parameters of a system causes a sudden qualitative change in its behavior or structure. This concept is particularly relevant when analyzing nonlinear systems, where small variations can lead to entirely different outcomes, illustrating the complex nature of these systems. Bifurcations can be seen in various contexts, from the dynamics of phase planes to feedback control, and they play a critical role in understanding how nonlinear control systems function.
congrats on reading the definition of bifurcation. now let's actually learn it.
