Fuzzy Variable Structure Attitude Maneuver Control and Active Vibration Suppression of Three-Axis-Stabilized Flexible Spacecraft
In this paper, a novel control system design strategy is investigated for the three-axis-rotational maneuver and vibration damping of a °exible spacecraft. Firstly, by using the lower order model, a robust fuzzy attitude control scheme based on Takagi-Sugeno (T-S) fuzzy control theory and variable structure control (VSC) technique is provided to design the attitude controller, which accomplishes attitude maneuvering in the closed-loop system. Secondly, strain rate feedback control methods are presented to suppress the induced vibration actively by using piezoelectric materials as additional sensors and actuators. 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.
