Analysis of synchronized behaviour of two metronomes: experimental verification

In this paper, we experimentally evaluate the performance of a method for theoretically analysing the synchronized behaviour of two metronomes on a hanging plate using the describing function approach, proposed in our previous work. This is because the performance evaluation for real systems is important for practical application, but it was not conducted previously. By applying the analysis method to an experimental system with real metronomes, we demonstrate that the analysis results similar to experimental ones are obtained even though there are some approximations associated with the use of the describing function approach. This indicates that our analysis method is applicable to the synchronized behaviour of real metronomes.
