Abstract:

Aiming at the defects of signal loss and poor adaptability of the classical washout algorithm when applied to flight simulator, an optimization scheme of washing algorithm based on multiple filtering signal compensation is proposed. Analyzing the lost signal in classical washout algorithm, intercepting the lost signals to the depth filter with depth filtering strategy, basing on human perception errors and platform movement margin, after multiple filtering signal to certain proportion respectively compensation to the three channel of washout algorithm to achieve the maximum reduction of signal loss, thus reducing human perception error. The classical washing algorithm and the improved washing algorithm are compared by simulation and experiment, the results show that the improved washout algorithm reduces the human perception error, reduces the loss of signal, improves the phase delay, makes full use of the motion platform work space, and increases the fidelity of the motion.
