Comparative Study Between a Novel Direct Torque Control and Indirect Field Oriented Control of Three-Phase Induction Motors

Three-phase induction motors are still dominant operators for many modern industrial applications. Many control methods implemented to control the speed and torque of induction motors in applications such as electric vehicles. The main objective of this paper is to compare the performance of a three-phase induction motor controlled by using a novel Direct Torque Control (DTC) method and Indirect Field Oriented Control (IFOC) method. MATLAB/SIMULINK program is used to make a complete computer model of the induction motor. Then, the speed of the computer model is controlled using a novel DTC and IFOC respectively. It is concluded that the novel DTC is suitable for constant reference speed applications, and IFOC method is suitable for applications that required variable reference speed.
