In this research the behavior of small-scaled wind turbine system is evaluated against strong wind input considering round trip delay. Generally, the wind turbine system is generating energy from the revolution of blades. The revolution of blades is depended on the velocity of wind. Therefore, if there is strong wind then the revolution of blade is increased and more energy will generated. Therefore, according to this situation the wind turbine systems are located in gale area in order to generate energy efficiency. However, there are specific limits of the revolution of blades or the angular velocity of blades. If the angular velocity exceeds the limit then wind turbine system may breakdown. Also, in this research time-delay element is considered due to the distance observation of behavior of system. Time-delay occur during the transposition of data between the observer and plant. Therefore, in this occasion round trip delay occurs in system. Hence, the closed loop of system may become unstable due to existence of time-delay element. Thus in this paper, in order to avoid the malfunction of wind turbine system and instability due to storm and time-delay element, respectively, restrained control is suggested. Restrained control is consist of pitch angle and axis friction control. The proposed method is to evaluate the restrained control with setting the reference angular velocity from low to high speed and different value of spring and damper. As consequences, for high speed reference signal and the restrained control contains better performance with strong damper.
