Due to physical laws or mathematical properties the states of some dynamic systems satisfy certain constraints, and taking advantage of such constraints generally will produce more accurate system models. This paper is concerned with dynamic modeling and state estimation of equality constrained systems. First, an effective framework for constrained dynamic modeling is proposed by which equality constraints...
This paper is concerned with the modeling problem of route-based motions. A typical route-based motion — straight-line motion — is modeled. Distinct from the conventional bottom-up strategy of the general motion modeling, the proposed modeling adopts a combination of top-bottom and bottom-up strategies. The process noises of the route-based motion model is discovered to be negatively correlated rather...
In air traffic control (ATC), aerial vehicles normally travel within scheduled route channels with certain probabilities. Exploitation of the probability-constrained route information intuitively will lead to enhancement of tracking accuracy and tracking continuity. This paper presents an ATC tracking approach by incorporating such information to improve the estimation performance accordingly. First,...
