K. Malanowski, STABILITY AND SENSITIVITY OF SOLUTIONS TO NONLINEAR OPTIMAL-CONTROL PROBLEMS, Applied mathematics & optimization, 32(2), 1995, pp. 111-141
Parameter-dependent optimal control problems for nonlinear ordinary di
fferential equations, subject to control and state constraints, are co
nsidered. Sufficient conditions are formulated under which the solutio
ns and the associated Lagrange multipliers are locally Lipschitz conti
nuous and directionally differentiable functions of the parameter. The
directional derivatives are characterized.
