Claim 0:
1. A digital closed-loop control system for use with an electrosurgical generator that supplies electrosurgical RF energy to a surgical site, the digital closed-loop control system comprising:
a feedback system for continually monitoring electrical properties of the supplied RF energy to the surgical site as a concurrent surgical condition and generating digital RF signals relating thereto; and
a microcontroller, responsive to the generated digital RF signals from the feedback system, is configured with a variable gain factor to regulate and control an RF amplifier that generates the supplied RF energy across a plurality of RF resolution settings and a plurality of RF regulation modes,
wherein the microcontroller is further configured to compute the variable gain factor for each of the plurality of RF regulation modes and select one of the computed variable gain factors based on individual error values calculated for each of the plurality of RF regulation modes; the variable gain factor being selected based on a most positive error value.
