Slew Maneuver Control of Flexible Spacecraft

Tekinalp, Ozan
Nonlinear slew maneuver algorithms for flexible spacecraft are developed. Theattitude trackingalgorithm that uses quaternion parametrizationand follows the prescribed time dependent attitude trajectory incorporating the derivative of the desired attitudeis employed. Nonlinear tracking feedback control algorithms that includes piezoelectric actuators and modal sensors are also developed. Through simulations, the effectiveness of the tracking attitude control algorithm is demonstrated. Also demonstrated is the effectiveness of the tracking controller utilizing piezoelectric actuators modal sensors in damping out vibration energy.
