Euler - Lagrange PBC NL Passive based control Energy PREFACE* Recently, in our country as well as in over the world, controlling Doubly-Fed Induction Generators in Wind power generators system (PĐSG) is a considerative problem. Now, there are some researchers who using a few control methods, such as: accurate * Tel: 0912 847588 156 linearazation[9], backstepping[1] and had gotten positive results. We ourselves also published searching projects in this field [2, 3]. This article introduces achievement of passivity-based control method to control Doubly-Fed Induction Generators in the case of grid failure. In details: Control .
