Abstract
A method and system are disclosed enabling configuration of a control system for an electrosurgical generator system for creating new surgical applications without changing the underlying software system. The electrosurgical generator system includes an RF stage to output at least one waveform of electrosurgical energy; a sensor module having at least one sensor to sense electrical or physical properties related to the output electrosurgical energy and generate sensor data; and at least one control module executable on at least one processor that controls at least one parameter of the output electrosurgical energy. The at least one control module includes an outer loop controller to generate a control signal in accordance with at least a first subset of the sensor data and an inner loop controller to generate a setpoint control signal and provide the setpoint control signal to the RF stage for controlling at least an amplitude of the energy output by the RF stage.
