Motion simulator usually appears the phenomenon of false cues and the workspace is limited in the process of washout.The proposed washout algorithm combines fuzzy logic control with the vestibular system to design the tilt coordination fuzzy adaptive filter,in order to minimize the vestibular sensory error below the human perception threshold.Owing to tilt coordination angular velocity limiter,the loss of low-pass acceleration must be compensated by the acceleration transform model.The translational channel decreases the possibility of the workspace beyond limitation and expands the scope of motion platform simulating input acceleration by using third-order filter.The simulation results show that the proposed algorithm can effectively overcome the phase retardation of classical washout algorithm,and then prevent the produce of false cues,decrease the displacement of motion platform simultaneously;in addition,white Gaussian noise simulates large variations in acceleration.The proposed washout algorithm can have maximal extreme value of acceleration and accurate simulating performance in general.It also proves that the proposed washout algorithm has a strong adaptability and reliability,which can effectively improve the dynamic fidelity for motion simulator.
