A Fractional-Order Sliding Mode Control to Compensate Sliding in Nominal and Underactuated Satellite

Today, the significant growth of fractional order accounts in engineering sciences has turned this branch into one of the most popular fields, especially for control engineers. Accordingly, several fractional order control methods have been designed. Also, if the necessary conditions are provided for the controllers, it has been shown that these types of controllers have the ability to control indeterminate systems despite disturbance. In this paper, the slid of a satellite is controlled and a strategy is proposed to compensate for the sum of slid and body position alters relative to the nominal and underactuated satellite. Due to the structure of the adj. utilized in this consider, for the reason of moving the lackey, the slid happens along the tomahawks of Y۴ and X۴. By applying the proposed strategy of remuneration for online slippage, the reenactment comes about clearly appear the position of the obsequious as much as the sum of slipping, after which the obsequious is set within the craved last position after applying the compensator.
