Abstract
An anti-windup technique for current control of Shunt Active Filters is presented. The main purpose of the proposed solution is to preserve the unconstrained tracking error dynamics, even under saturated conditions. A suitable modification of current references is imposed through the design of an additional dynamics. The proposed approach is valid for any kind of controller adopted to steer SAF current; in this work it has been applied on an internal model based controller. A variant of the basic approach is proposed to improve performances. Simulation tests confirm the effectiveness of the presented solution.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
