Robust Backstepping Speed Controller of a Doubly Fed Induction Motor using State-Space Nonlinear Approach

Authors: ,

Abstract: The aim of this paper is an efficiency Backstopping speed controller with direct stator flux orientation of doubly fed induction motor (DFIM) fed by two PWM inverters with separate DC bus link, the Backstopping controller is designed based on the Lyapunov stability theorem, by introducing the approach for decoupling the motor’s currents in a rotating (d-q) frame, based on the state space input-output decoupling method. The purpose is therefore to make the speed and the flux control resist to parameter variations, because the variation of parameters during motor operation degrades the performance of the controllers. The proposed approach is analysed by Simulink/Matlab environment. The simulation results show good performance and robustness.
