<p>LOAD SHARING SYSTEM Control systems for controlling load division among plural power sources coupled in parallel and providing power to a common load using feedback techniques. Control systems for various types of plural power sources are disclosed, including DC generators, hydraulic variable displacement pumps and AC generators driven by a constant speed drive. The outputs of the individual power sources are responsive and proportional to individual input control signals. The magnitude of a power component common to all the power sources or frequency, if the power sources are AC generators driven by constant speed drives, is compared to a reference to provide an error signal. Individual sensors sense the magnitude of a variable power component from each power source and provide a signal proportional thereto. Individual signals representing the variable power component are combined with the error signal to provide the individual control signals for each power source.</p> |
