Autonomous method and system for minimizing the magnitude of plasma discharge current oscillations in a hall effect plasma device

A system for minimizing the magnitude of plasma discharge oscillations of a Hall effect plasma device, the system comprising:

• a power processing unit configured to provide magnet current and power to the plasma device to establish plasma discharge current;
• a plasma discharge current measurement circuit configured to measure plasma discharge current oscillations;
• and
• a closed loop controller responsive to measured plasma discharge current oscillations configured to iteratively adjust the magnet current delivered to the plasma device in response to the measured plasma discharge current oscillations to reduce the magnitude of plasma discharge current oscillations.
