ABSTRACT
Power networks are large-scale spatially distributed systems located over widespread areas. Reliable monitoring and control systems are essential for guaranteeing the safety and stability of power networks. This chapter focuses on nonlinear power networks subject to the time delay switch (TDS) attacks. It establishes an effective method to countervail the negative influence from TDS attacks. To more effectively monitor system states and vulnerability to TDS attacks, the chapter propose an augmented observer system to ensure that the estimation error system is the finite-time boundedness. The elimination of negative effects, from the TDS attacks to the system performance, is achieved by means of a compensation control. In the T-S fuzzy modeling, several operating points are selected for a considered nonlinear system. The corresponding local subsystems are obtained for each operating point of the identification or linearization technique, where subsystems are connected with a fuzzy inference rule together with a membership function.
