Self-excited vibration

from Wikipedia, the free encyclopedia

One speaks of self-excited oscillation when the energy supply is controlled by a suitable control element and the oscillation process itself. Mathematically, such an energy supply can be realized, for example, by a special damping term in which the damping can become negative. Such a system is mostly non-linear. An example of this is the van der Pol oscillator .
