Bang-singular optimal control: second order conditions and a shoooting algorithm

Venerdi' 9 Marzo 2012 - Maria Soledad Aronna


Venerdi` 9 marzo 2012 alle ore 12:15 in aula 2BC30 Maria Soledad Aronna (Universita` di Padova) terra` un seminario dal titolo "Bang-singular optimal control: second order conditions and a shoooting algorithm".

In this work we study optimal control problems for systems affine in the control variable. We consider bound constraints on the control, and finitely many equality and inequality constraints on the initial and final state values. First, we obtain second order necessary optimality conditions. Secondly, we derive a second order sufficient condition for the scalar control case.
Afterwards, we propose a shooting algorithm and we give a sufficient condition for its convergence. We show a link between this sufficient condition and the one obtained above. In some problems, we are able to analyse the stability of the optimal solution under small perturbations and the inversibility of the Jacobian matrix of the shooting function associated to the perturbed problem.
