The combined-maximum principle in problems of estimating the motion parameters of a maneuvering aircraft

Abstract

The synthesis of an optimum tracking filter for a maneuvering aircraft, a problem that is considered an inverse dynamic problem, is studied on the basis of the combined-maximum principle. The filter equations are obtained without the use of the method of invariant immersion. It is shown that the estimates of trajectory parameters that are obtained via application of the new tracking filter possess higher accuracy characteristics than the estimates of the extended Kalman filter and considerably decrease the amount of computations.
