Path Following Strategies for Nonlinear Systems

Design of feedback controllers for the path following may be considered from two points of view. First, by separating the geometric and time information of a path, path following may be seen as a subproblem of trajectory tracking (Coelho and Nunes 2005). Second, looking at the controlled states, path following may be a part of stabilization (Canudas de Wit et al. 1996).
