Flux Observer-Based vector control for Induction Motor

2013
Student Projects

Abstract

The induction motor offers the best value for money and is therefore used in many different application fields where power requirements are higher than a few kilowatts. ln order to be able to reduce the priee and the motor's size, a control algorithm based on an estimation of the flux without speed sensor for a Brushless AC motor (BLAC) has been developed in the Professer Shen's lab. The objective of this project is to examine the possibility to adapt and then implement this sensorless control algorithm to the induction motor. The induction motor's specificities will have to be analysed carefully in order to be able to propose an adapted control solution which will be implemented and tested on an induction motor.

Electric motor

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

AC motor

An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings.

Induction motor

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable, and economical.
