Behaviour planning and control of active sidestick system

Compared with the passive sidestick used in traditional aircraft, the active sidestick system improves the pilot's situational awareness and helps the pilot quickly respond to emergencies. In this paper, the common working modes of the active sidestick system are designed and the conditions and logics for mode transition are designed based on the finite state machine. Then the control scheme of the active sidestick system is designed, and the control method is designed for the system in the active mode. The final simulation results show that the designed system can well control the sidestick displacement and feedback force, and verify the state transition effect under the active mode and the effectiveness of the shake mode.
