Iterative learning control of three-phase pulse width modulation voltage source rectifier

Abstract

Iterative learning controller is studied for three-phase pulse width modulation voltage source rectifier. In any bounded initial input conditions, the designed controller can repetitively update input according to output error-tracking until it converges to zero. The controller is able to deal with dynamic systems with imperfect knowledge and has strong robustness and immunity. The convergence of the learning control rules in iteration domain is guaranteed with rigorous proof, and the simulation results demonstrate the effectiveness of the presented method.
