Abstract:
The federated and fuzzy adaptive filter is composed of the federated filter and the fuzzy adaptive filter which has been improved. To adjust the structure coefficient and algorithm for the new innovation of the matching filter, the federated and fuzzy adaptive filter adjust the weight of locally estimated state on the velocity matching and the angular rate matching in the transfer alignment by the difference between the real innovation variance and the theory innovation variance. And it guarantees the stability of matching filter and the accuracy of transfer alignment. The result of simulation shows that the feder-ated and fuzzy adaptive filter is better to estimate the initial attitude misalign-ment angle of inertial navigation system (INS) when the system dynamic model and noise statistics characteristics of inertial navigation system are unclear.
