Design and MATLAB Simulation Modeling using Digital control system Techniques of Direct Torque Control drive of Three 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 mathematical model of 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 (00) to 2 (3600) 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.
