Abstract

Abstract: The key of the fidelity of flight simulators lies in the merits of the washout algorithm; the classical washout algorithm has been widely applied owing to its convenient parameter adjustment as well as rapid feedback and execution speed. However, the classical washout algorithm still exists some certain defects in its structure design, which will cause exaggerated phase retardation error and false cues thus resulting in the deterioration in dynamic fidelity of flight simulators. According to vestibular perception system, the structure redesign of the classical washout algorithm was carried out, using the compensation theory to reduce its phase retardation and false cues. In the MATLAB/SIMULINK, simulation verification was conducted on a set of actual flight data, and then presented the range of optimal parameter value. Simulation results show that the optimized washout algorithm within the range of optimal parameter value can enhance the utilization rate of motion platform and reduce the false cues, so as to improve the dynamic fidelity of flight simulators.
