5-axis centralized hover control and considerations to stability of single-rotor helicopters with optimal state feedback by Naomichi ISOMURA, Takayuki SHIOKAWA, Daigo FUJIWARA

“…In the comparison with the distributed control system using the Single-Input Single-Output (SISO) controller which is common approach for flight control, this full-axis centralized control system includes the effects of cross-coupling dynamics and enables a design for full control-axis at once in a short amount of time. …”
