    摘要: A fuel cell APU system comprising a plurality of fuel cell modules connected in parallel. Each module includes a local controller connected to a master controller that coordinates the modules to achieve a desired power output at any given time. Each module is operated within an output range to maximize efficiency of the system. When load demand on a first module exceeds the desired output range of the module, an additional module is brought online in parallel with the first. As the load increases further, additional modules are brought online in cascade fashion to permit all modules to be operated efficiently. If a module is disabled, it is automatically switched out of service and replaced by a standby module. The master controller keeps track of the total operating time of each module and varies the sequence in which different modules are brought into service to balance deterioration among the modules.

    摘要: Small engine control is provided in which a manual selection of an engine operating level, such as from a positioning of a movable selector between a discrete number of selection settings is used to reference open-loop fuel, air, and ignition timing commands for application to respective actuators in accord with simple yet accurate and flexible engine control. Control precision, sensitivity, and stability are enhanced through engine parameter feedback control, wherein any of the open-loop air, fuel and ignition timing commands may be adjusted in accord with a difference between a feedback signal and a target value.
