چكيده عربي :
The principle operation of speed control systems is depended upon a wide range of generated frequencies a microprocessor was used to generate PWM or a six-steps modulated signal to maintain a constant voltage/frequency ratio. Because of speed computation limitations found in many available microcomputers previously, it was concluded that the on-line computation of switching patterns was not practical. The control and monitoring by using PC is more efficient and active.
