When a plastic bottle with water is placed upside-down with a thin pipe at its head, limit-cycle oscillation can be observed. A simple differential equation can reproduce the properties of this oscillation. In the present study, a three coupled oscillator system is investigated experimentally and numerically. The behavior of the three coupled oscillators with frustration is interesting from the viewpoint of mathematical physics, and with an increase in size, this system should be helpful in unconventional computing, such as in, for example, optimization problems.

Keywords: Limit-cycle oscillation, synchronization, coupled oscillators, frustration.
