boost 컨버터에 퍼지제어기를 적용한 조류 발전의 MPPT제어

초록

In this paper, the control method of extracting maximum power from the seaflow energy is proposed. This paper describes a variable speed seaflow generation system with permanent magnet synchronous motor, bridge rectifier, boost converter and Fuzzy controller. In this proposed seaflow generation system, the duty ratio of buck-boost converter is controlled by the fuzzy controller. An advantage of MPPT control method presented in this paper don’t need to use the characteristic of seaflow turbine at various seaflow speed and measure the tidal speed and the rotating speed of tidal turbine. Therefore, the proposed system has the characteristics of lower cost, higher efficiency and lower complexity. The effectiveness of algorithm is simulated based on Matlab Simulink.
