A prototype 3kW horizontal upwind type wind turbine generator of 4m in diameter has been designed and examined under real wind conditions. Usually the machine is controlled at several stages depending on both the measured rotational speed and the calculated wind speed. Two control methods have been applied: the variable pitch angle, and regulation of the generator field current. To improve the control program on a high wind speed stage, the pitch angle controller adopted a LQG (Linear Quadratic Gaussian) control method. This paper describes the LQG controller and shows a numerical simulation result. The control program varied the pitch angle and maintained a optimum rotational speed to prevent over rotation past 400 rpm.
