generate very wide bandwidth waveforms directly and efficiently. With chaos control, we can produce a vast array of waveforms that are ideal for spread-spectrum communications and for highly accurate ranging. We believe a system designed around a chaotic source can perform comparably to conventional systems while requiring far fewer components. The idea of exploiting the complexity of chaos in order to simplify hardware is the crux of chaos engineering. For these applications, the oscillators and controllers must operate at frequencies at and above several hundred megahertz. To control chaos at these speeds, we certainly cannot employ digital processors or complex analog circuitry to calculate the requisite control perturbations: the extremely short latency demanded of the feedback loop necessitates a simple controller. Besides such practical concerns, the true efficiency of chaos control is suspect if the controller is considerably more complex than the system under control. Hence, we believe the development of simple control techniques—such as limiter control and dynamic limiting—is essential for the development of practicable chaos engineering. In summary, we have described a circuit for generating chaos along with an active limiter that can be used to stabilize periodic states using efficient chaos control. We have used this limiter to stabilize period-1 and period-2 orbits in the circuit, and have shown that the magnitudes of the control perturbations are minimal when controlling these natural
