Abstract
The frequency of self-excited systems depends on the amplitude and under the large amplitude, the excited frequency deviates from the natural frequency. Therefore, to keep the excited frequency near the natural frequency, the response is required to have a small stable steady amplitude. In this paper, a self-excited cantilever beam of Van der Pol type is realized by using nonlinear feedback and the dependence of the response amplitude and frequency on the nonlinear feedback gain is theoretically examined.
