The Cooperative Control of tracking and vibration suppression of Flexible truss with Twin-Gyro Precession

EasyChair Preprint no. 3685

Abstract

This paper presents a composite control approach which both can track the desired trajectory and suppress vibration of a flexible truss undergoing a long-duration slewing motion. An improved PD state feedback master controller is proposed to implement such tasks as sinusoidal slewing tracking, which has advantages of wide dynamic range, high accuracy, fast response and little overshoot compared to the conventional PD controller. Moreover, an auxiliary direct modal force compensator is formulated to dissipate the vibration of flexible truss. With the composite strategy, the tracking performance can be further improved so that the whole system achieves the cooperative control. The simulation results demonstrate the validity and effectiveness of the combining control strategies.
