Indirect field oriented speed control of an induction motor drive using Takagi-Sugeno type of fuzzy logic controller

The field oriented control of induction machine is widely used in high-performance applications. The primary advantages of this approach are the decoupling of torque and flux characteristics and easy implementation. Detuning caused by parameter disturbances still limits the performance of these drives. In order to accomplish variable-speed operation, a conventional controller is used. The conventional controllers provided limited good performance over a wide range of operation, even under ideal field-oriented conditions. In my thesis Takagi-Sugeno type fuzzy logic controller is used. It can operate in all range. The scheme is compared with conventional controller and results are validated by simulation.
