Inverse control for nonlinear excitation and governor control

This paper presents the results of a study of the Inverse Control technique for the design of excitation and governor controllers for a power system. Control laws for rotor angle and field flux are derived. The closed loop system is shown to be asymptotically stable. The system can be transferred to a new operating condition corresponding to any desired terminal voltage Vl and tie-line power P_tie. Although this control law was not experimentally tested on a power system, implementation issues are discussed in robotic and aerospace applications.
