摘要

Several different control theories have been designed for the problem of the satellite attitude control. According to presence of uncertainties in the space missions, adaptive control techniques are useful. In this paper, the satellite attitude control problem is studied using a novel optimal adaptive controller. The new control method is developed based on rotation matrices. This optimized adaptive controller uses Markov parameters. The controller is a direct adaptive controller which is applicable for following the control command. Also, for comparison, fuzzy control of satellite attitude is included. Finally, the results of simulations indicate that the desired conditions are achieved by the satellite, and the response of the system utilizing the fuzzy control method is faster than when the mentioned adaptive controller is used.
