Abstract
This thesis discusses the implementation of a signal induction motor speed control system based on the use of microcomputer to generate driving signals to a signal-phase full-bridge inverter which feeds the motor by the pulse modulation (pm) wave form.The thesis consists of five chapters described briefly as follows:
Chapter (1) discusses some introductory concepts to the speed control of induction motor and givessome steps for determining a new voltage/frequency relation to be used with the single-phase induction motors as the constant volts/hz relation is unapplicable due to the exist of the background field. Also some of the essential considerations involved in the design of a microcomputer controlled pulse modulated inventer, with connection on minimizing hardware requirements and performing as many functions as possible in the softqare.
Chapter (2) discusses some of the PMswitching strategies and relate these strategies to the developments of the microcoprocessor.Also a software program is designed to analyze theharmonic elimentation PWMstrategy to obtain the switching instsnts and study the harmonic contents of the output wave form.
