Variable Structure Model Reference Adaptive Controller applied to a synchronous generator control

In this paper is presented an alternative control strategy where rotor angle and field flux of a synchronous generator connected to an infinite-bus power system is controlled by a variable structure model reference adaptive controller. A decoupling theory is used on the synchronous generator model to obtain two subsystems, where rotor angle and field flux can be controlled independently. Simulation results are presented for the synchronous generator decoupled model and compared to the coupled synchronous generator controlled by a classical proportional-integrative-derivative controller.
