In this paper a nonlinear predictive control using optimal control is applied to the current control of a three-phase four-wire shunt active power filter. The control law has closed analytical form and on-line dynamic optimization is avoided, the control law is easy to implement. Three phase currents are sensed and then transformed to synchronous rotating reference frame, positive and negative load currents distortions are extracted and regarded as reference currents of the active power filter… CONTINUE READING
