Abstract

The problem of transient stability for a single machine infinite bus system (SMIB) with uncertain parameters in the turbine steam valve control is addressed by means of combining the direct fuzzy logic system and the backstepping method in this paper. Since the process of the controller design is without any linearization, the nonlinear property of the dynamic is preserved. The problem of parameter uncertainty is effectively resolved by fuzzy logic system. Finally, the results of simulation show the effectiveness of the proposed method.
