Claim 19:
20. The plasma system of claim 19, wherein the controller is configured to:
determine a first one of the plurality of offsets for which a first amount of power is reflected towards the HF RF generator;
determine a second offset value for which a second amount of power is reflected towards the HF RF generator, wherein the first one of the plurality of offsets and the second offset value are associated with one of the plurality of time intervals of the cycle;
compare the first amount of power to the second amount of power to determine that the first amount is less than the second amount,
wherein to determine the plurality of offsets, the processor is configured to select the first one of the plurality of offsets instead of the second offset value.
