Microprocessor based optimal digital positron control with A-C squirrel cage motor

Abstract

The aim of this project is to adjust the speed of a three phase squirrel cage induction motor to any desired value between zero and its rated value, using power elect ronics components and a microcomputer, and to develop a controlling system which will be able to transfer a load from any initial position to a. desired position in minimum time, under some restrictions. The main parts of the system are, a microprocessor, a converter, an inverter, a main control unit, a three phase squirrel cage induction motor and a tachometer.
