Event-triggered optimal fuzzy control of power system

In this paper, the state feedback fuzzy optimal event-triggered control scheme is investigated for simple interconnected power system when system states are measurable. By using the Takagi-Sugeno fuzzy model, the fuzzy model of the power system is established. In terms of and parallel distributed compensation (PDC) technology, the local fuzzy optimization controller is designed. The sufficient conditions which ensure the stability of the power system are given in the form of linear matrix inequality (LMI). According to Lyapunov stability theory, the system stability is proved. Simulation results demonstrate the proposed control scheme can realize the optimal control of the power system.
