Abstract: A comparison between the performance of the two control algorithms, Adaptive neuro-fuzzy inference system based on least mean square (ANFIS-LMS) and hyperbolic tangent function-based on least mean square (HTF-LMS) control algorithm for three-phase DSTATCOM (Distribution static compensator) is presented in this paper. A Shunt compensator consists of a three leg VSC (voltage source converter) and a zigzag transformer to eliminate the defects caused by the loads which are nonlinear in nature, in three-phase systems. The ANFIS-LMS-based control algorithm estimates reference supply currents by extracting fundamental components of active and reactive power and the hyperbolic function control algorithm based on LMS enhances the convergence rate with the noise suppression in the power systems. The DSTATCOM prototype is developed in real time and implementation is performed on DSP (Digital signal processor). Simulation is done in MATLAB environment, resulting in the HTF-LMS based control algorithm that is much faster than the ANFIS-LMS based algorithm with a more reduced static error rate.
