Abstract :
Based on field acceleration method control of an induction motor and a novel digital PWM (pulse width modulated) inverter technique, a novel induction motor variable-frequency, variable-voltage drive system is presented. Knowing the slip frequency and motor speed, the amplitude of an induction motor terminal voltage can be calculated using a program, and in turn, the time periods of the PWM inverter can also be determined. The control algorithm has been implemented with an Intel 8096 microcontroller. Experimental results, obtained using a 0.5 hp induction motor, demonstrate an excellent speed response characteristic, which confirms the validity of this control strategy.<>
