Abstract
Control schemes for controlling a gas turbine engine in response to disturbances associated with a load mechanically coupled with the gas turbine engine are provided. In one aspect, a gas turbine engine mechanically coupled with a load has a controller that includes executable control logic. The control logic includes a feedforward module, an aggressive control module, and a power turbine governor module. By executing the modules, the controller seeks to maintain a constant power turbine speed stably and subtly in response to small disturbances associated with the load and aggressively in response to large disturbances associated with the load, as well as smooth transitions between the responses.
