Abstract

In this paper, a new direct torque control (DTC) scheme for a doubly fed induction motor (DFIM) powered by two voltage source inverters is designed and implemented to improve the dynamic response and performance of the system. The conventional DTC scheme of the DFIM is widely used due to its high performance, robustness and simplicity of implementation. However, the electromagnetic torque and the flux controlled by classical DTC have high ripples. To overcome these drawbacks and to ensure fast response and full reference tracking with the desired dynamic behavior and low ripple level, the combined DTC-backstepping control using a backstepping controller is developed and validated; this strategy is based on the Lyapunov theory to ensure a robust control, less sensitivity from machine parameter variation and without overshoot, unlike the classical PI controllers. The proposed DTC scheme will be investigated by simulation tests using Matlab/Simulink and experimental implementation using dSPACE DS1104 board. Results obtained by simulation and experimentation show the effectiveness of the proposed control in terms of rapidity, robustness and stability for the DFIM operating at variable speeds.
