Jacobi Fields in Optimal Control: One-dimensional Variations

  • 2 Accesses


In this paper which is closely related to the previous paper [3] we specify general theory developed there. We study the structure of Jacobi fields in the case of an analytic system and piecewise analytic control. Moreover, we consider only 1-dimensional control variations. Jacobi fields are piecewise analytic in this case but may have jump discontinuities. We derive ODEs that these fields satisfy on the intervals of regularity and study behavior of the fields in a neighbourhood of a singularity where the ODE becomes singular and the Jacobi fields may have jumps.
