Speed control of three phase induction motor is important for industry. For speed control of induction motor
mainly three control methods are employed namely Scalar control, Field oriented control (FOC) and Direct Torque
control (DTC). Scalar control method is generally not used in application, where accurate torque response will required.
In all the operating conditions the behavior of FOC scheme is characterized by lower values of the three-phase rms
current ripple. In DTC scheme a better torque response can be achieved in terms of settling time. Here Simulations and
Results of both FOC and DTC technique have been carried out.
