ABSTRACT. We constructively prove the existence of a robust adaptive nonlinear dynamic feedback control for a synchronous generator connected to an infinite bus, which does not require the machine internal voltage measurement and relies on the well-understood third order model nonlinearities but not on several critical parameters. Boundedness and L and L2 transient performance are guaranteed; asymptotic speed and terminal voltage regulation are achieved in the case of permanent constant parameter perturbations.

1. Introduction

The transient stabilization and voltage regulation problem of power systems consists in the design of an excitation control which keeps the angular speed of each generator close to the synchronous speed and regulates its terminal voltage to the desired ...
