Speed Control of an Induction Motor by Using Indirect Vector Control through PI Controller

The MATLAB model of  speed control of induction motor by using indirect vector control through IP speed controller is represent in this model ,cage type 50 HP induction motor is use for representation of this model. The field orientation theory is take place for detailed studies of this model in simulation. Motor speed control by using  PI control in Field orientated control (FOC) drives. .In induction motor scalar control  have some limitation which is overcome by the field orientation control . The indirect vector controlled induction motor drive involve dissociate of the stator current in to torque and flux producing components.
