Direct Quadrate Modeling of a Direct Torque Control for a 3-Phase Induction Motor

This paper presents a Direct Quadrate (D-Q) model of a Direct Torque Control (DTC) for a 3-Phase Induction Motor (IM) using MATLAB Simulink. The impact of various loads on the 3-Phase IM were also studied and simulations were carried out using MATLAB Simulink. The simulation results show that the estimated stator flux angle varies from 0 rad (0
⁰
) to 2n rad 360
⁰
) with an approximate frequency of 50Hz. The steady state estimated stator flux module fluctuates from the reference value with an error of 0.525% maximum ripple. Results obtained from the simulations using the proposed model indicate that the model gives a better performance in comparison with conventional Direct Torque Control models.
