Summary:
In the system of the LC van der Pol oscillators star-coupled by one resistor, N-phase oscillations can be stably excited when N is prime number and the strength of nonlinearity of the system is sufficiently large. In this case, the system exhibits (N - 1)! different stable states, and it is considered that it can be used as some kinds of neural networks and associative memories. If we use the system as neural networks, the control of the phase pattern should be an important problem. To achieve this, we have proposed the oscillators systems with pulse driving units. In this paper, we show that we can derive all the possible phase patterns with at least N - 2 pulse stimulation units.
