Abstract

A new way has been proposed in this paper to design a nonlinear feedback linearized controller for a single-input-two-output control problem of a multi-input multi-output system. An islanded AC microgrid linearized by the feedback linearization control scheme. The output voltages and currents are the control objectives to improve the voltage regulation and the power-sharing accuracy among parallel-connected distributed generation systems, respectively. The stability of the proposed feedback linearized control scheme has been investigated using a Lyapunov function for the islanded AC microgrid. The performance of the designed nonlinear controller has been evaluated under different case studies for the islanded AC microgrid.
