Abstract

The control of DC motors requires providing a variable DC voltage which can be obtained from DC choppers of controlled rectifiers. these voltage controllers are simple and less expensive. Dc motors are relatively expensive and require More maintenance,due to the brushes and commutators. However, DC drives are used in many industrial applications. AC motors exhibit highly coupled, nonlinear, and multivariable structures as opposed to much simpler decoupled structures of separately excited DC motors. The control of AC drives generally requires complex control algorithms that can be perfomed by microprocessors and/or microcomputers along with fast switching power converters. The ac motors have a number of advantages ; they are lightweight (20 to 40% lighter than equivalent dc motor), Inexpensive, and of low maintenance compared to DC motors. They require control of frequency,voltage, and current for variable-speed application. The power converters, inverters and ac voltage controllers, which are relatively complex and more expensive, require advanced feedback control technicques such as model reference, adaptive control, sliding mode control, and field oriented control. However, the advantages of AC drives outweight the disadvantages. There are two types of AC drives : inductions motor drives and synchronous motor drives. The speed and torque of induction motors can be varied by one of the following means :1.stator voltage control, 2. Rotor voltage control, 3.frequency control, 4.stetor voltage and frequency control, 5. Stator current control, 6. Voltage, current, and frequency control. To meet the torque-speed duty cycle of a drive, the voltage, current and frequency control are normally used. In this paper will introduce the motor induction control with rotor voltage control method.
