Plasma impedance matching

Dear all,

is there any one with plasma background?

I am developing an algorithm for a plasma impedance L type matching network.

Initially, I set the Load and Tune units to some specific positions. The algorithm is simply tuning a possible minimum SWR starting from the initial position towards the minimum or maximum position of the units and set back to a position where minimum SWR occurred.

This works for non- plasma loads. But, while testing with plasma, after completing the tuning and setting back to the exact position where minimum SWR happened, it results in largely different SWR and high reflected power reading. I couldn't find out why this happens.

would you help me please?
Thank you a lot.
