Abstract : "This paper presents a novel control strategy for the tip position and vibration control of a class of space
flexible structures. The proposed control algorithm consists of finite frequency H∞ vibration control technique and
fractional-order PDn control technique. More specially, a new finite frequency H∞ controller working in the inner
feedback loop is proposed to suppress vibration modes and external disturbances, and a new fractional-order PDn
controller is developed in the outer feedback loop to guarantee the desired position tracking performance. Compared
with conventional methods, the proposed one could achieve better control results. Finally, an illustrative example is
presented to demonstrate the robustness and effectiveness of the proposed composite control strategy. system. Based on Lyapunov method, stability analysis and design conditions of the resulting closed-loop"
