    Abstract

    Many nonlinear electronic systems are susceptible to chaos as a result of the break-up of a homoclinic orbit in the state space dynamics. We review a method by which input signals that are best possible at inducing complex dynamics, includ- ing chaos. These forcing functions are then used to investigate a practical problem relating to complex dynamics in a nonlinear system: how to achieve in- band disruption of a common nonlinear circuit, the phase-locked loop. This problem is chosen both for its intrinsic interest and as a motivational example of how such optimal forcing functions can be used to understand better complex dynamics in practi- cal nonlinear systems. Numerical and experimental results are reported for a prototypical circuit to val- idate our approach.
