摘　　要：提出采用最优节点的样条函数模型对复杂误差建立数学模型,该模型通过最优节点个数和节点距的自适应调整,精确分离复杂误差数据中的次低频误差和随机误差,对次低频误差通过样条参数的统计模型实现,对随机误差采用自回归模型实现,并综合得到复杂误差数据的仿真。最后,利用该仿真模型讨论了复杂误差对数据融合系统输出精度的影响。The paper presents the mathematic modeling of complicated error by optimal knot spline function, which can automatically separate not only the error with secondary low frequency but also the stochastic error from complicated error data. The simulation of the error with secondary low frequency is carried out by statistics modeling of spline parameters, the stochastic error by autoregressive modeling, and at last the simulation of the complicated error is integrated. As an application, the precision of data fusion processing system is discussed by including the complicated error.
