Indirect sliding mode control of a three-phase active power filter

The objective of this paper is to compensate the harmonic pollution due to power electronic converters by using the sliding mode control. In this way, a control scheme based on a new switching selection table is proposed. This method is able to reduce the sensitivity of the compensator to variations in system parameters which results in an improvement in the system's robustness. In the paper, comparative simulations are carried out to show the validity of the proposed method.
