Nonlinear control of a Permanent Magnet Synchronous wind Generator

Abstract

This work presents a nonlinear control of a wind generator equipped with a Permanent Magnet Synchronous Generator (PMSG). Three SISO controllers are developed, a Passivity based controller for the PMSG and its converter, and two Lyapunov controllers for the DC link and for the grid side converter, respectively. A general Control Strategy is presented in order to pass severe faults as symmetrical grid voltage dips. The proposed controllers are tested under realistic wind conditions.
