The proposed control system includes the attitude controller acting on the rigid hub, designed by using pulse - width pulse - frequency ( pwpf ) modulation integrated with command shaping technique based on csvs method, and the piezoelectric material elements as sensors / actuators bonded on the surface of the beam appendages, designed by the optimal positive position feedback ( oppf ) control technique, in which the selection of ppf gains is determined via introducing a cost function to be minimized by feedback gains which are subject to the stability criterion at the
設計的控制器僅利用輸出信息，從而避免設計撓性模態狀態觀測器以及引入狀態觀測器誤差;在此基礎上，採用分力合成方法設計命令成形控制器來抑制撓性附件的振動，設計的優化命令成形控制信號在理論上可以對系統的各階撓性模態完全抑制。但考慮到模型不確定性和外部擾動，在內迴路又設計了最優正位置反饋（ oppf ）補償器以增加撓性結構的阻尼，使撓性結構的振動能夠很快衰減。
