Abstract :
This paper proposes a novel high performance vector control system of AC motor using a low switching frequency (2 kHz) PWM voltage source inverter with an output LC filter. Excellent high-speed response characteristics of the LC filter output voltage have been realized using a novel deadbeat control algorithm. As the experimental results, the torque current response that is similar to the response of the system without a LC filter has been obtained. In addition, it has been confirmed by simulation that errors of the LC filter constants within /spl plusmn/10% can be permitted.
