Abstract:
High power converters, such as three-phase inverters, usually operate at low frequencies due to the switching losses. Besides, modeling errors and non-linear loads with unmodeled dynamics can degrade the controller performance resulting in a poor transient response and instability. A robust model reference adaptive controller (RMRAC) for three-phase uninterruptible power supplies (UPS) is presented. The three-phase system model is rewritten, using a synchronous transformation in dq coordinates, and a RMRAC controller is used to assure system robustness and performance. Simulation and experimental results are used to show the closed-loop system robustness and performance under several operation conditions.
