H_∞ Variable Universe Fuzzy Control for Power System

Abstract:

The paper proposes a new power system stabilizer based on adaptive variable universe fuzzy systems. The algorithm creates the bridge to supply H_∞ control design with more intelligence and fuzzy control design with better robust performance. By Lyapunov method, the overall closed-loop system is shown to be stable. In this study, the effect of both fuzzy logic approximate error and external disturbance on the tracking error is attenuated to a prescribed lever ρ by adequately selecting the weight factor γ. The statement is confirmed by simulation results of a single-machine infinite-bus system and a multi-machine system.
