On phase pattern transition in star-coupled Wien-bridge oscillators with parameter deviations

摘要

In this study, we investigate the basins of attraction of the phase patterns and clarify the effect of parameter deviations in pulse-driven star-coupled Wien-bridge oscillators with parameter deviations. From the simulation results, it is shown that some phase pattern can be seen easily and the others can be hardly seen because of the deviations. Moreover, the reachability problems of the phase patterns suggests that these systems can treat not only the spatial phase patterns but the spatio-temporal patterns.
