Abstract : In this article, an adaptive fuzzy finite time command filter control scheme is first proposed for a single machine infinite power system with static VAR compensator (SVC). The unknown external interference is taken into account in the controller design, and the incomplete single machine infinite SVC power system is formulated in terms of fuzzy logic system. The devised adaptive backstepping control scheme employs command filter technology and finite time control theory. Further more, it is proven that the designed controller ensures the rotor power angle in the power system converge to the expected value and all variables of the control systems are semi-global practical finite-time stable (SGPFS). Finally, simulation results are presented to show the effectiveness of the proposed control scheme.
