Abstract


In this paper, a new nonlinear observer for the synchronous machine damper currents is developed. The observer design is based on the theory of Lyapunov of nonlinear systems. The stability of the proposed observer is shown to be Globally Exponentially Stable (GES) in the context of Lyapunov theory. The paper also describes how to design the observer gain, and includes computer simulation results to demonstrate the effectiveness of the proposed observer.
