Research Abstract	The energy stored in a flywheel is rotational kinetic energy. The flywheel itself is obviously a key component of the FESS. More recently, carbon-fiber composites have been used as the flywheel material. In this case, the flywheel can spin at a much higher speed and the speed of the flywheel provides the greatest contribution to the energy storage capability of the system. The design of the rotor can have a significant effect on the performance of the system, research continues on the design of a modern composite rotor. Thus a higher rotating speed can be safely attained with a consequent higher energy storage capacity. At first, the new FESS was designed , fabricated and assembled. Next, the simple adaptive control was applied to FESS and also variable bias control algorithm was applied to FESS
