| Abstract: | A DDC slip frequency vector-control system using a 8-bit microprocessor for variable frequency speed-control of induction metor with a Ac-Dc-Ac current source inverter is presented. In the system, dual mode control is used to meet the need of quick response and PWM control of variable forms is provided to operate smoothly atlow speed. The function of microprocessor is fully utilized. The practical method of the system hardware and software is provided. The system processes the features of reasonable design, simple structure and flexibility. Some diagrams and the experimental results are shown. |
