Outline of Final Research Achievements |
Injection-locking of nonlinear oscillators to an external periodic forcing is a fundamental phenomenon which adjusts their frequencies to that of an external forcing. Such injection-locking enables to stabilize the frequency of the oscillator, and it has a long history and produces a large variety of applications. In our research, we develop a method for maximizing the frequency range of an external forcing sustaining the injection-locked mode (i.e., locking range or synchronization band), based on our newly developed optimization theory. As a case study of optimizing synchronizability, we design the input waveforms that maximize locking ranges in an injection-locked Class-E oscillator, by using our optimization theory. Further, we verify the optimality of these inputs through systematic numerical calculations and experiments.
