Adaptive Finite-time Fuzzy Control for Synchronous Generators in Nonlinear Power Systems with Time-delays

In this research, the problem of finite-time adaptive fuzzy control based on state-feedback for nonlinear power electrical systems with time delays is considered. By applying fuzzy logic systems (FLSs), the obstacles appeared in unknown nonlinearities is moved. With the utilization of finite-time Lyapunov stability theory, an adaptive backstepping excitation control design is developed. Through Lyapunov analysis and choosing appropriate Lyapunov-Krasoviskii functionals, the presented controller can guarantee that the variables in the closed-loop systems are all bounded in finite time. Simulation results are provided to illustrate the correctness of the theoretical results.
