| Abstract |
The microprocessor control of PWM inverters used for variable-speed induction motor drives offers new ways to obtain better performances. A low harmonics content of the inverter current over a wide range of frequencies, and a fast system response are the most important requirements to be met. The approach of this paper is based on uniform sampIing using both on-Iine calculations and look-up tables containing results of off-line calculations. An interrupt-driven multitasking software configuration is developed and tested. The software testing techniques used have been instrumental in choosing a better configuration for the real time control system. The microprocessor controlled PWM transistor inverter has a wide frequency range (0.5 Hz - 100 Hz) and the harmonics content of the output current is very satisfactory over the full range of operation. |
