The DTC-SVM scheme with Takagi-Sugeno fuzzy controller for three-phase Induction Motor

This paper proposes the direct torque control scheme with space vector modulation and Takagi-Sugeno fuzzy controller (TSF). In conventional DTC-SVM scheme, two PI controllers are used to generate the reference stator voltage vector. To improve the drawback of this conventional DTC-SVM scheme is proposed the TSF controller to substitute both PI controllers. The proposed controller calculates the reference quadrature components of the stator voltage vector. The rule base for the proposed controller is defined in function of the stator flux error and the electromagnetic torque error using trapezoidal and triangular membership functions. Constant switching frequency and low torque ripple are obtained using space vector modulation technique. Performance of the proposed DTC-SVM with TSF controller is analyzed considering different operating conditions. The simulation results shown that the proposed scheme ensures fast torque response and low torque ripple, these results validate the proposed scheme.
