Control problems in a superconducting turbogenerator

The paper takes into consideration the possibility to employ the classical methods of the optimal control theory for the design of a rotor regulator useful for superconducting turbine generators. To this aim, at first a simple dynamic model of this kind of generators is shown and a method for the determination of its parameters is mentioned. Then an observer, able to give the not measurable state variables, is obtained. Finally the goodness of the observer operation is checked by simulation, taking into account the design data of a two-pole, 1500 MVA turbogenerator.
