本文通過引入新息相關法，提出了一種基于新息相關性自調整的交互多模型算法。該方法首先利用模型概率識別出最可能近似真實模式的模型，而后針對該模型應用新息相關法濾波，在系統(tǒng)的數(shù)學模型和噪聲的統(tǒng)計模型不精確的情況下，通過監(jiān)測殘差是否為白
噪聲，來相應地調整卡爾曼增益，從而使卡爾曼濾波達到最佳。

Abstract: a new IMM algorithm based on the auto-adjustable correlation of the residual is
provided. The algorithm first recognize the most probable model that near real mode by using
model probability, then filter for the recognized model using the correlation of the residual. The lgorithm adjust Kalman gain ,by monitor whether the residual is white noise when the system’s athmetical model and the statistical model of the noise are not accurate, so that Kalman filter is ptimal.
