| Abstract |
This paper proposes a hybrid control algorithm for a power quality conditioning device. This algorithmincorporates a Linear Quadratic Regulator (LQR) to a Robust Model Reference Adaptive Controller(RMRAC) in order to obtain a high performance and robust system of control for the specified plant.The RMRAC controller is developed to deal with parametric variation and system uncertainties, whilethe LQR scheme is designed to deal with disturbances caused by high line impedance. Thus, the hybridcontrol structure guarantees a good tracking performance for the plant to be controlled, considering ahuge class of uncertainties, commonly found in real systems. The power conditioning topology consistsof a Shunt Active Power Filter (SAPF), that uses a three-phase three-legs Voltage Source Inverter (VSI),connected to an L filter. |
