Study on fuzzy adaptive variable structure attitude controller design

In this paper, a novel control system design method was introduced for the three-axis-rotational maneuver of a rigid spacecraft. By using the lower order model, a robust fuzzy attitude control scheme based on Takagi-Sugeno (T-S) fuzzy modeling and variable structure control (VSC) technique is provided to design the attitude controller, which accomplishes asymptotic attitude maneuvering in the closed-loop system. Numerical simulations are performed to show that rotational maneuver and vibration suppression can be accomplished in spite of the presence of disturbance torque and parameter uncertainty.
