Occasional Delayed Feedback Control for Switched Autonomous Systems

We propose the occasional delayed feedback control for chaotic circuits with interrupt characteristics. The control input generated by the difference between the current state and the delayed state is added to the system occasionally, i.e., during a certain interval defined by the switching policy. This control is reasonable for chaotic systems including some switches since they are not always feasible to admit the control input, e.g., a fixed control input terminal may be separated according to the switching action. We apply the control method to a chaotic switched circuit and demonstrate availability by some numerical experiments.
