Methods and system are provided to mitigate RF interferences during operation of an electrosurgical system. An electrosurgical system configured to output therapeutic RF energy may refrain from outputting RF energy in order to measure an RF interference for a group of candidate frequencies, and to select a frequency from the group of candidate frequencies for which the measured RF interference is below a threshold value, and to produce a feedback signal (a control signal) at the selected frequency to control operation of the electrosurgical system. During operation of the electrosurgical system the feedback signal may be filtered by a BPF whose fundamental frequency is set to the selected frequency, to thus obtain an interference free feedback signal and, consequently, a reliable control of the electrosurgical system.
