Abstract
In this work, an adaptive vector controller is designed for a three-phase voltage source converter (VSC) to provide power factor compensation. The method relies on a third-order non-linear model of the VSC, which includes parametric uncertainty. The proposed method ensures asymptotic tracking of the q-axis current using an inner loop, which contain two proportional-integral (PI) controllers that have adaptive decoupling terms. The output of an outer loop PI controller for dc voltage defines the reference for the d-axis current control. The asymptotic stability of the closed-loop is proven using Lyapunov's method. The performance of the proposed method is evaluated in the simulation and experiment, and results show improved performance and ease of controller tuning.
