Adaptive robust DSP-based single phase AC power source

Abstract

Presents an adaptive robust DSP-based single phase AC power source, which is able to generate sinusoidal waveforms with adjustable amplitudes and frequencies over a wide range, as well as several arbitrary waveforms. The setup is based on a DSP-based pulsewidth modulation (PWM) inverter. To guarantee good response and robustness of the system, a robust model reference adaptive controller is used. The performance of the proposed control strategy is demonstrated by experimental results under several load conditions.
