In this paper, an online EMD (Empirical Mode Decomposition) based algorithm is proposed for the control of a shunt AF (Active Filter). Standard EMD algorithm has worked on the principle of time scale difference between the upper maximum values and lower minimum values of a signal, and for a long time it has been considered good for offline analysis of signals. This paper deals with the real time application of EMD for the control of AF under balanced and unbalanced loads. Linear interpolators are employed for constructions of upper and lower envelopes to avoid computation complexity. Moreover, customized iterative computations for extraction of IMFs (Intrinsic Mode Functions), maintain the efficiency of algorithm. The algorithm extracts the fundamental oscillating component of load current and helps in estimating reference currents. Simulations are performed on a MATLAB/ Simulink platforms. Simulated results are verified with test results of a developed prototype of shunt AF.
