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. Keyphrases: active control, cooperative control, state feedback
