Abstract
The realistic motion of the vehicular simulator is produced by the motion cueing algorithm. An optimal washout filter, taking into account the limitation of the simulator's workspace, is applied here to minimize human's perception error in order to provide realistic behavior. The filtering algorithm compares the human's perception of driving simulator with that driving actual vehicle obtained based on the human vestibular model. The cost function accounting for both the pilot's sensation error and the range of platform motion is minimized to achieve more realistic motion and efficient usage of the limited workspace. To compensate the drawback of fixed parameters in optimal washout filter, the fuzzy control rules of motion perception are applied to online adjust the filtered signals. The simulation results verify the efficient utilization of platform workspace and less sensation error compared with that obtained by the classical washout filter. © 2011 IFAC.
