    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.

    Abstract: Provided are systems and methods of controlling load share in a multi-engine propulsion system. A load share participation value indicative of a load share participation regime for a first engine may be received and a load sharing requirement control command for the first engine may be output. The load share participation value may depend or be based at least in part on one or more operating conditions of a second engine. The load sharing requirement control command for the first engine may depend on whether the load share participation value indicates a full-participation load share regime for the first engine, a partial-participation load share regime for the first engine, or a non-participation load share regime for the first engine.
