On a small scale wind energy conversion system (WECS) which are installed in area with low wind speed, pitch angle on a blade is an important method in the power regulation. With a constant position of the blade, wind turbine which is installed on the low speed wind field 5-7 m/s causes the produced power of the wind turbine not optimum. In that case multi input multi output plant requires control system design to be more complex. In order to overcome that condition, it is important to develop intelligent control based on fuzzy logic. In this paper, the design of fuzzy logic control (FLC) is performed, which is implemented on a small scale wind turbine system operated on a low wind speed. The analysis is carried out by visualize and define the correlation between wind power, power of wind turbine, and electricity power which are produced by system and optimisation criteria of the control system and system performance as well as linked compromises between controlled power and the limited actuation of nod angle.
