Abstract

The aim of this research is to reduce down the angular velocity against strong wind during the storm considering the distant observation. Our expectation of this small-scaled wind turbine is to operate continuously even in storm days. However, since the small-scaled wind turbine consists of small blade, it may exceed the limitation of angular velocity in storm condition due to the low inertia moment and consequences of centrifugal force. So it would be broken down the system. Our target is to somehow reduce down the angular velocity using the stall factor control. Stall factor control mainly used in the junction of axis of blade of wind turbines gear wheel. Subsequently, the stall factor is operated when the angular velocity exceeds the limitation. Therefore, adaptive controller is designed and in order to evaluate the angular velocity’s behavior phase space method is introduced. As consequences, the stall factor preserves the stability and angular velocity performs under desired value constantly.
