Active Harmonic Current Controlling Using HInfinitive Controller
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 11
Abstract
In this paper cascaded current – voltage control technique proposed for DC-AC converters in distribution generation (DG) units. The main objective of the proposed controller is to improve the power quality by injecting a clean sinusoidal current to the grid even in the presence of local non-linear loads. This proposed controller consisting of inner voltage control loop and outer current control loop with both the controllers is designed by using H-infinitive repetitive control strategy. By this proposed controller, the THD value reduced and improved tracking performance. In order to verify the improvement of performance, the simulation results of the proposed controller compared with current control strategy in the conventional controller is done by using the MATLAB/Simulink.
