Sensitivity analysis for relaxed optimal control problems with final-state constraints

Coauthors: Joseph Frédéric Bonnans, Oana Silvia Serea

 

Abstract:
We consider a family of relaxed optimal control problems with final-state constraints, indexed by a perturbation variable y. Our goal is to compute a second-order expansion of the value V(y) of the problems, near a reference value of y. We use relaxed controls, i.e., the control variable is at each time a probability measure. Under some conditions, a constrained optimal control problem has the same value as its relaxed version.
The specificity of our study is to consider bounded strong solutions [2], i.e., local optimal solutions in a small neighborhood (for the L\infty-distance) of the trajectory. To obtain a sharp second-order upper estimate of V, we derive two linearized problem from a wide class of perturbations of the control (e.g., small perturbations for the L1-distance). Relaxation permits a very convenient linearization the problems. Using the decomposition principle [1], we prove that the upper estimate is an exact expansion.
