Direct Torque Control of Three Phase Induction Motor

Direct Torque Control (DTC) uses an induction motor model to predict the voltage required to achieve a desired output torque. By using only current and voltage measurements, it is possible to estimate the instantaneous stator flux and output torque. An induction motor model is then used to predict the voltage required to drive the flux and torque to the demanded values within a fixed time period. Electrical and Electronics students can use this project report for there final year project. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.

Model of DTC

The DTC method provides robust and fast torque response without such coordinate transformations, PWM pulse generation and current regulators. Moreover, DTC minimizes the use of motor parameters. This thesis proves that DTC technique is easier to implement and keeps the variables within the range. This thesis presents a study of DTC technique for voltage source inverter fed induction motor drives using MATLAB.

In this project the Simulink model and results that validates the DTC principle has been presented. The objectives of the project are to prepare a simulation model of a induction motor & to simulate the Direct Torque Control (DTC) of Induction Motor (IM). Use this project report for your reference and study work only.
