We introduce a new method of controlling chaos that retains the essential f
eatures of occasional proportional feedback, but is much simpler to impleme
nt. We demonstrate control on a simple piecewise-linear Rossler circuit ope
rating near 1 kHz and a Colpitts oscillator with a fundamental frequency of
19 MHz. As a result of the simplicity of our technique, control of chaos h
as been accomplished for the fastest chaotic system reported to date.
