Abstract:

The research covered several aspects of the basic issues that are needed to develop and implement nonlinear and hybrid systems schemes for the filtering, tracking, and control of maneuvering vehicles in an uncertain and nonlinear geometry. It is based on the approximation of the original nonlinear problem by a switched Markov linear models which in turn lead to hybrid model formulation or to piecewise linear approximations. Four aspects are considered 1 Approaches to handling hybrid systems models 2 Fast and slow decomposition for piecewise linear systems 3 Estimation in the presence of impulsive inputs that can serve as either models for the switching behavior or the changes in maneuvers 4 Modeling, parameterization, and realization issues for hybrid systems. Applications to nonlinear filtering and tracking schemes and their implementation is also addressed.
