COMPARATIVE STUDY OF BACKSTEPPING AND PROPORTIONAL INTEGRAL CONTROLLER TO COMPENSATING CURRENT HARMONICS

Abstract

This paper presents and compares the performance of two control techniques namely backstepping and Proportional Integral PI applied to a voltage source inverter operating as an active power filter. The controller permit to compensate harmonics and reactive power generated by the non-linear load simultaneously. This work is performed in order to make an accurate comparison of backstepping controller and classical control technique such as PI controller. The backstepping controller . The obtained results show the backstepping controller is performing much better than the PI controller over a wide operating range.
