1. A method for controlling an electrosurgical generator, the method comprising the steps of:

  • outputting electrosurgical energy;

    measuring impedance to obtain at least one measured impedance signal;

    filtering the at least one measured impedance signal to detect an arcing condition; and

    adjusting a PID gain of a controller of the electrosurgical generator to adjust the output of electrosurgical energy in response to the detected arcing condition without terminating the output of electrosurgical energy.
