| Abstract: | A demonstrating experimental device of inverted pendulum driven by periodic force is designed and constructed. Using developed software, this system can demonstrate the state of motion and automatically record and save the data of the time series. Changing the length of the pendulum and the driving voltage, we can observe the process of the period-doubling bifurcation route to chaos. |
| Keywords: | inverse pendulum demonstration system period-doubling bifurcation chaos phenomenon |
