飞行模拟器洗出算法的改进及实现

An improved washout algorithm and it's realization for the flight simulator

为了使飞行模拟器能够在有限的工作空间内为飞行员提供逼真的动感,针对Stewart运动平台,研究了与之相应的体感模拟算法(洗出算法).针对经典洗出算法存在的缺陷提出了相应的改进方案,同时基于Matlab-Simulink建立数学模型,在此基础上,做了飞行动作曲线的仿真和分析.通过对比分析改进前后的洗出算法,验证了改进后洗出算法的准确性和有效性.

To provide the fidelity motion cues for pilots in the flight simulator motion space,this paper presents an improved algorithm based on the classical washout algorithm.The algorithm is built on Matlab platform.Through this model and the actual flight data,the simulation result is gotten.Compared with the classical washout algorithm,it proves the accuracy and effectiveness of the improved algorithm.
