Abstract
Within both a method for operating an internal combustion engine and a system for operating the internal combustion engine there is provided an engine rotation speed pulsation damping within the internal combustion engine through use of a PID controller which varies a single PID control parameter, particularly, K to provide the engine rotation speed pulsation damping within the internal combustion engine. Within both the method and the system there is also provided a pair of control algorithms for use within the PID controller such as to effect the desired engine rotation speed pulsation damping when operating the internal combustion engine.
