Energy based sliding mode control of Brushless Double-fed Induction Generator

Abstract In this paper, a novel robust control scheme for a Brushless Double-fed Induction Generator is presented. The mathematical model for the electrical machine is developed, based on the Hamiltonian energy function, including the mathematical description for a wind turbine. Furthermore, in order to add robustness and taking into account the energy properties of the system, the Integral Sliding Mode control technique is proposed, to guarantee the rejection of the system perturbations. Then, a passive state feedback control law is applied, to stabilize the closed-loop system. The proposed combination is able to reject the system perturbations and stabilize the system in the desired operation point.
