Chaos and chaos control in a strongly driven thermionic plasma diode

In a periodically driven thermionic diode period doubling cascades, period adding and low-dimensional chaos are found. Some dynamical properties of the driven discharge are comparable to strongly driven diode resonant circuits. The chaotic oscillations of the discharge current are controlled using occasional proportional feedback and an improved difference feedback method. Feedback constants are predetermined by the local analysis of the first return map.
