Design and analysis of a high performance three-phase voltage source inverter based on fuzzy logic controller

This paper presents a design of a three-phase voltage source inverter (VSI) using fuzzy logic controller to improve the performance of VSI. In the design of VSI controller, triangular and bell shape membership functions are integrated with seven linguistic variables (LV) for the two inputs and one output controllers. MATLAB/SIMULINK has been utilized to develop the proposed system. Results revealed robustness of the designed VSI in terms of minimum percentage mean square error, minimum integral time square error, and minimum integral time absolute error. In addition, the analysis shows that the proposed controller can follow the reference voltage quickly to achieve the steady state value compared to that of traditional VSI with PI controllers. Therefore, VSI based on FLC is more suitable to implement in PV power generation systems.
