An adaptive type-2 fuzzy logic system controller has been designed for LFC in a nonlinear time-delay power system.
A Lyapunov–Krasovskii functional candidate has been used to evaluate the stability of the system.
Adaptation laws for the type-2 fuzzy logic system controller parameters have been derived from the Lyapunov–Krasovskii functional candidate.
A two area nonlinear and time-delay power system has been considered for simulations.
