In this paper, we have compared the parameters of the Wind Energy Conversion System (WECS) using different controllers. Controllers in WECS are implemented to control a permanent-magnet synchronous generator (PMSG) that is powered to load through a converter. First priority of controllers is to extract maximum power output under fluctuating wind speed. Controllers such as pitch controller, PD, PID and FLC are applied to variable speed WECS models in MATLAB SIMULINK. Output using different controllers provides comparison between relative parameters like settling time, rise time steady state error and power factor. Result also provides performance of controllers in steady and transient state. Pitch angle is the controlling parameter for all the controllers which is important to eliminate possible danger due to sudden change in wind speed
