Abstract
Systems and methods are provided for controlling a power plant during use of a power take-off (PTO) device, wherein the responsiveness and stability of the controller are adjustable by an operator in the field. The use of setting maps allows fine tuning of controller responsiveness while also ensuring that expected performance would be achieved at any setting within the setting map. In some embodiments, a proportional-integral-derivative (PID) controller is used to control engine speed, and gains for the proportional, integral, and derivative terms are obtained from setting maps based on a responsiveness setting chosen by a vehicle operator.
