The proposed LMF based control algorithm has been implemented for the harmonics extraction from the sinusoids. It is considered better from existing conventional algorithms (SRFT, IRPT etc.) in ways that it involves simple computation, easy to implement as it makes use of simple mathematical blocks for calculation whereas SRFT and IRPT involve complex blocks, more stable, takes less time to settle and is proved to be more reliable. The simulations were performed in the environment of MATLAB/SIMULINK.
