Microalternator Experiments to Verify the Physical Realisibility of Simulated Optimal controllers and Associated Sensitivity Studies

It is shown experimentally that modern control theory can be used to provide very satisfactory excitation control of a microalterntor intended to represent a large, 2-pole, fossil fuel, thermal unit, under a wide range of operating conditions. Five different controllers are considered and experimental work is supported by extensive digital computer simulation and associated parameter and trajectory sensitivity studies.
