Practical Constraints

In this paper an examination is made of the performance characteristics of a scheme of chaos control using optimised impulsive delayed feedback. The scheme is applied in a model of external cavity laser diodes giving attention to the application of the feedback via modulation of the laser drive current taking into account practical constraints arising from technical delay and the frequency in application of the control signal. It is demonstrated that by use of a so-called ∊-ball condition chaos control is achievable in the fully developed coherence collapse regime without preliminary targeting dynamics to an unstable orbit.
