Research on Double Input Motion Somatosensory Algorithm Based on Logic Control

Aiming at the two-input classic washout algorithm in the flight simulator, there are problems such as loss of perceived angular velocity signal, phase error, and insufficient fidelity. A logic control washing-out algorithm is proposed. Based on the vestibular system theory, the classic washout algorithm is used to improve the high-pass angular velocity channel structure. A logic controller and an angular displacement continuous generator are designed to optimize the coupling angular velocity in the high-pass angular velocity channel and the tilt coordination channel and stabilize the jump change washout angular displacement, so the improved algorithm is more consistent with the human perception model. The improved algorithm is modeled and simulated in Matlab/Simulink. The simulation results show that the improved washout algorithm reduces the phase error and false hints, and improves the fidelity of angular velocity dynamic simulation.
