A single-phase AC power source using robust model reference adaptive control

This paper presents a 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 computer-controlled pulse width 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 various load conditions.
